Strays feel the bite as pandemic spreads  

AFP / ANGELOS TZORTZINISThe global lockdowns against the coronavirus are tantamount to a death sentence of stray cats and dogs
As coronavirus forces billions of people around the world into lockdown, another sizeable population has also been hard hit -- stray animals.
While pet owners in many countries are still allowed to walk their dogs, thousands of other animals -- the exact numbers are unknown -- are starving and turning feral.
The mass closure of restaurants has also deprived hungry animals of leftover meals, forcing them to take greater risks.
For many, the restrictions are tantamount to a death sentence.
"We are seeing an increase in the numbers of cats in areas where we feed, some appear to have been abandoned, while others have roamed far from their usual spots in search of food," says Cordelia Madden-Kanellopoulou, a co-founder of Nine Lives Greece, a network of volunteers dedicated to reducing the overpopulation of stray cats in Athens and other cities.
According to the municipality, the stray dog population in Athens is put at hundreds while the cats run into the thousands.
"It is a huge worry to us that strays could be exposed to more cruelty and poisoning, being more visible and hungrier now, and thus more likely to trust and approach people," said Madden-Kanellopoulou.
Greek officials over the weekend said an online platform had been created for food donations and veterinary services for strays and pets whose owners are unable to care for them.
"During the lockdown, we make sure that all dogs have enough food so that they don't become aggressive. This week we will also start installing feeders in different areas of the city making sure that dogs and cats are fed regularly," said Serafina Avramidou, city of Athens councillor for animal welfare.
Avramidou said she has also already signed more than 350 permits for volunteers to visit feeding areas without getting fined.
In neighbouring Turkey, authorities in Istanbul distribute around a tonne of food for street cats and dogs every day.
- 'We'll care for your friends' -
"We were taking care of strays even before the coronavirus," Tayfun Koc, an Istanbul municipal feeding worker, told AFP.
"I say this to all our citizens, stay at home, we will take care of our little friends," he said.
AFP / ANGELOS TZORTZINISEuropean authorities are realising that allowances must be made for populations of stray animals
Authorities elsewhere in Europe are gradually realising that allowances must be made for stray populations.
After Spain went into a nationwide lockdown on March 14, Madrid officials closed down 125-hectare Retiro park in the city centre where around 270 cats live in 19 different colonies.
For days, volunteers were not able to enter. City hall authorities eventually allowed them to give food to park gardeners to distribute.
A single volunteer may also enter the park three times a week, for an hour at a time, to check on the health of the cats.
Mercedes Hervas, the president of the Association of Friends of the Cats of Retiro, says this was not enough time to check on them all and look after those in need of medical care.
On March 30, a park employee found dead a female cat that the group had been treating with antibiotics. Hervas predicted other cats would also die.
"You have to go from colony to colony and wait for the cat to come out. Maybe Olympic athletes can do it in one hour, we can't," she says.
Elsewhere in the Balkans, provision is more ad hoc.
In Serbia, where there is no state-organised effort to feed and shelter stray animals, people in several cities and towns have organised help locally.
A similar effort is under way in North Macedonia where NGOs are calling on people to leave food on the street for the estimated 10,000 stray dogs in Skopje.
In Croatia, about 40 animal shelters which had to close their doors for visitors are imploring citizens not to abandon their pets.
In Albania, locked-down citizens say it is impossible to secure permission to walk a dog, let alone feed strays, so people go out in secret.
- 'Death sentence' -
"These measures taken for humans are effectively a death sentence for dogs and cats," says Indrit Osmani who heads the Animal Rescue Albania volunteer group.
AFP / ANGELOS TZORTZINISPets are not entirely safe even at home
In Bulgaria, veterinary clinics ran an information campaign after pets were increasingly found on the street because their owners thought they may transmit the virus.
There was a similar campaign in Beirut, where Lebanese animal rights groups have reported an increase in abandoned pets.
The group, Beirut for the Ethical Treatment of Animals, last week said it had received "countless" calls concerning poisonings across the country, mainly around the capital.
Last month, it said that the number of abandoned pets had "at least tripled in recent weeks because of the panic" caused by the virus.
But in a time of heightened health concerns, pets are not entirely safe even at home.
French veterinarians last week warned owners against attempting to disinfect their dogs and cats with detergent or alcohol gel.
The move came after images online showed dogs whose legs had been burned by disinfectants.
"Soapy water or a dog shampoo works very well", said Christine Debove, regional adviser of the Order of veterinarians for Ile-de-France.
Not only are dogs and cats unable to digest alcohol properly, but these products can also cause respiratory irritation and skin reactions, Debove said.

Updated , July 12, 2024

ANKARA, Turkey (AP) — Turkish President Recep Tayyip Erdogan’s ruling party submitted to parliament Friday a controversial bill aimed at managing the country’s large stray dog population. Critics are concerned that the proposed legislation will results in dogs being confined to cramped shelters and potentially lead to the killing of many of the animals.

The bill is pitting animal rights activists against those calling for measures to make the streets safe from the feral dogs.

Erdogan has said that an estimated four million strays are roaming Turkey’s streets and countryside.

The legislation is a watered-down version of an initial proposal, which reportedly called for the strays to be rounded up, housed in shelters and euthanized if they are not adopted within 30 days. That proposal, which was not submitted to parliament, had ignited a public uproar, with animal rights activists arguing it would result in the mass extermination of unadopted dogs.

Abdullah Guler, a senior legislator from the ruling party, told reporters that under the revised proposal, stray dogs would be removed from the streets and placed into shelters where they would be neutered and spayed.

The dogs that are at risk of rabies, exhibit aggressive behavior and have no possibility of being rehabilitated would be euthanized, Guler said.

Municipalities would be required to enhance and improve conditions in existing shelters while people would be encouraged to adopt the dogs, the legislator added.

Erdogan’s ruling party and its nationalist and Islamist allies hold a majority in parliament and the bill is likely to pass when it reaches the floor. No date has been set.

A report released by the Safe Streets and Defense of the Right to Life Association, an organization campaigning for the removal of all stray dogs from the streets, says that 65 people have died in street dog attacks since 2022.

The government promised to tackle the issue earlier this year after a child was severely injured after being attacked by dogs in the capital Ankara.

Despite existing legislation that requires stray dogs to be caught, neutered and spayed, and returned to the spot where they were found, a failure to implement those regulations over the past years has caused the feral dog population to explode, animal rights groups say.

They argue that proper implementation of these regulations would be sufficient to control the population.

Britain has recently issued a stray dog warning for travelers to Turkey, stating that they often form packs and can be aggressive. It has advised visitors to be cautious and avoid
approaching them.

ANKARA (Reuters) - Turkish police scuffled with protesters in the capital Ankara on Friday during a demonstration against plans to round up millions of stray dogs.

The plan, presented to parliament by President Tayyip Erdogan's ruling AK Party earlier this month, has alarmed animal lovers who say a mass neutering campaign would be a better solution than locking dogs up in shelters.

Police pushed back the protesters as they tried to gather in the city centre, leading to scuffles.

The demonstrators held banners reading, "You cannot round them up, you cannot jail them, you cannot kill them" and "Take back the law".

"People here are those taking care of many animals. What is this grudge? Do you want the dogs and cats on the street to be killed?" one protester said through a megaphone.

Under the draft law, municipalities would be charged with moving strays off the streets and into shelters until they are adopted. Aggressive dogs or any with untreatable diseases would be put down.

The population of street dogs in Turkey is estimated to be 4 million, and 2.5 million dogs have been neutered in the past 20 years by municipalities, according to the draft bill.

There are currently 322 animal shelters with a capacity to host a total of 105,000 dogs, the bill says.

Thousands protest in Istanbul against bill they fear will lead to mass cull of stray dogs

Thousands of people have gathered in Istanbul to protest against proposed legislation that critics fear will lead to the mass killing of stray dogs across Türkiye.

The draft bill aims to regulate the country's millions of stray dogs and make streets safer but animal rights advocates are concerned many animals would be put down or end up in neglected, overcrowded shelters.

Demonstrations against the bill, which was proposed in mid-July, have been an almost-daily occurrence for the past several weeks as the proposed legislation makes its way through the judicial system.

A parliamentary committee approved the draft earlier this week, and the full assembly is scheduled to have a final vote in the coming days with deliberations starting on Sunday.

The government estimates that around four million stray dogs roam Türkiye's streets and rural areas.

Although many are harmless, numerous people, including children, have been attacked in Istanbul and elsewhere.

The proposed legislation mandates that municipalities collect stray dogs and house them in shelters where they would be neutered and spayed.

Dogs that are in pain, terminally ill, pose a health risk to humans or are aggressive would be put down.

Municipalities would be required to build dog shelters or improve conditions in existing ones by 2028.

The legislation is a watered-down version of an initial proposal, which reportedly called for the strays to be rounded up, housed in shelters and euthanised if they are not adopted within 30 days. That proposal, which was not submitted to parliament, sparked a public uproar, with animal rights activists arguing it would result in the mass extermination of unadopted dogs.

But animal rights activists worry that some municipalities might kill dogs on the pretext that they are ill, rather than allocate resources to shelter them.

The government denies the bill would lead to a widespread culling and the country's justice minister said anyone killing strays "for no reason" would be punished.
Why does Türkiye need to control its stray dog population?

A report released by the Safe Streets and Defense of the Right to Life Association, an organisation campaigning for the removal of all stray dogs from the streets, says that 65 people have died in street dog attacks since 2022.

The government promised to tackle the issue earlier this year after a child was severely injured after being attacked by dogs in the capital Ankara.

LICENSE OWNERS NOT DOGS
Ban on XL bully dogs ‘will leave abandoned strays roaming the streets’
ITS THE OWNER NOT THE BREED

Joe Pinkstone
Sat, 4 November 2023

Don't Ban Me - License Me spokeswoman Sophie Coulthard with her XL bully Billy - Paul Grover

The ban on XL bully dogs could lead to a large number of them being abandoned on the streets as strays, charities have warned.

It will be illegal to sell, breed or abandon an XL bully type dog from Jan 1 2024 and it will be an offence to own one from Dec 31 unless the animal is registered to the Index of Exempted Dogs.

In the latest incident on Friday, two people were taken to hospital with serious injuries after an attack by a suspected XL bully.


One woman reportedly fell out of the window of the flat where the attack happened on Friday night in Mansfield, said Nottinghamshire Police.

The large dog, believed to be an XL bully, was seized from a nearby property and taken to secure kennels.

Campaigners against the ban on American XL bully dogs have launched a legal challenge to the Government asking for the planned ban to be scrapped in favour of tightening laws around breeding and owning dogs, and educating owners.

Campaigners from Don’t Ban Me – License Me, largely made up of XL bully owners, have raised more than £50,000 towards a Judicial Review and plan to ask the Department for the Environment, Food and Rural Affairs (Defra) to rethink its plans to ban the breed.

John Cooper KC, the campaigners’ barrister, sent a Pre-Action Protocol in Judicial Review to Therese Coffey, the Environment Secretary, last Thursday, Nov 2.
Knee-jerk reaction

He said “It was a knee-jerk reaction done too quickly without proper consideration of the evidence – much of the evidence hasn’t been examined at all, and some of it is wrong.

“The public must be protected, but the Government’s decision does not protect them. The Dangerous Dogs Act of l99l didn’t stop dog bites or fatalities – in fact there are more fatalities and bites now than then.

“The way forward isn’t to add XL bullies to the banned list, but for owners to have proper control over their animals, and for there to be severe penalties for dog owners who don’t take their responsibilities seriously.

“Vets being asked to euthanise any XL bully dogs who don’t have an exemption certificate by the end of January 2024 say they can’t administer it. This ban is an ill thought-out mess.”

The ban has been called a “death sentence” and some charities, such as Dogs Trust, have already said they will not take in any more XL bully dogs because they have a policy of never putting down a healthy dog..

Animal charities told the Telegraph that any dogs in their care in 2024 will most likely have to be euthanised because it would be unethical to keep them in a kennel for the rest of their lives, which is the only other option, and many shelters are already full.

As a result, there are fears owners forced to relinquish their dogs will abandon them on the streets because it is the best chance the animal has at survival.

An owner can have the dog euthanised by a vet and get £200 compensation from the Government, or the dog can be given to a charity for rehoming until the end of the year. A charity will get £100 compensation from the Government for euthanising an XL bully.
Unscrupulous owners

The more unscrupulous owners may also opt for at-home destruction of animals too, to avoid veterinary costs, now the business of breeding and selling XL Bullys is outlawed.

Dr Sam Gaines, head of the companion animals team at the RSPCA, told the Telegraph: “It is now our fear that, as a result of this ban, we will see more dogs being abandoned and surrendered.

“In most cases, we expect that owners who are not going to be able to keep their dogs will do the responsible thing and not just abandon them on the street, but I think we have to expect that there will be some dogs that will be abandoned.

“We are going to end up with lots of authorities that are going to have to go out and collect those dogs and then euthanise them.”

Coventry council has reportedly seen a small rise in the number of stray XL bully dogs already this year. It is the statutory duty of the local authority to collect stray dogs where they are kept in a council pound for a week and their owners sought. In normal cases the stray will enter the rehoming process after seven days but if the dog meets the XL bully definition then it will be destroyed as of 2024.

However, some councils have already said they will not collect a stray dog if it is suspected it is an XL bully. Colchester and Cumberland councils have said the dog is too dangerous for their staff to collect and are in talks with their local police forces to help collect suspected stray XL bullys, for example.

‌This will add an additional burden on the dog units of local police forces which will be tasked with assessing if every XL bully in the country meets the definition laid out by Defra this week.

‌The definition of what an XL bully is includes descriptors of head size, height, muscularity and other physical features but was made without the input of the leading UK dog experts who withdrew from talks with the Government because of concerns it was too vague and broad a description.

‌The Government’s definition could also cover non-XL bully breeds, the experts say, with other bulldogs, mastiffs and some mongrels likely to inadvertently meet the XL bully criteria.

‌“Defra has been told that one of the big unintended consequences of having a broad definition is that potentially hundreds of thousands of dogs are going to be caught up in this,” Becky Thwaites, head of public affairs at Blue Cross, told the Telegraph.
Increased levels of euthanasia

‌Since the ban was formally announced on Tuesday, shelters have seen a surge in inquiries, with owners of an XL bully trying to figure out the best course of action.

‌“We’ve already been taking an increased number of calls from owners who are really worried about what this announcement means for them,” said Ms Thwaites.

‌“There’s going to be thousands of dogs who are going to be coming into organisations like ourselves, and it’s going to be a real challenge to rehome them. Ultimately, these pets are going to have to be put to sleep based purely on a law that we know actually isn’t even going to improve public safety.

‌“We are planning for increased levels of euthanasia over the next three months.”

‌She added that staff in the rescue sector are distraught at the prospect of spending months killing thousands of XL Bully dogs.

‌“I think we’ve got to be very realistic that the likelihood of being able to rehome some of these dogs is going to be very, very difficult,” Ms Thwaites said.

‌“The only thing we can do [with surrendered XL Bullys] is to keep it in a kennel for the rest of its life and that is not something from a welfare point of view that we could ever do.

‌“We aren’t able to provide the stimulation that a dog would need. It is a death sentence for dogs, that much we know.”

Restored stream supports new wild salmon run


Study confirms salmon of Putah creek origin for first time

Almost everywhere in California, salmon are on the decline. But in Putah Creek — a restored stream running through the University of California, Davis, campus — wild salmon are not only increasing, they also are completing their life cycle.

A UC Davis study, published in the journal Ecosphere, is the first to document Putah Creek-origin salmon. Chinook salmon have been observed at the creek since 2014, but prior studies had shown them to be strays from hatcheries. This study now confirms that some salmon returning to Putah Creek in the fall to spawn are actually born there.

This should not be news. Salmon are famous for their simple life cycle: Hatch in a stream, migrate to the ocean, and return to the stream to spawn at their life’s end. Yet salmon in 21st century California are sometimes trucked or flown to the ocean from hatcheries due to dams, habitat loss, warming streams, drought and other threats restricting their natural migration.

This study shows that at Putah Creek — and potentially other altered and dam-controlled streams worldwide — restored waterways can help restore and even create salmon runs.

“The fact that you have Putah Creek-origin fish is a big deal,” said senior author Andrew Rypel, director of the UC Davis Center for Watershed Sciences at the time of the study. “To have a growing, stable population that’s natal means it’s a well-managed ecosystem. It means we’re taking care of the water and the land the right way, and that there’s a future for fish in that place. It also shows there’s hope for other streams that are degraded.”

Water brought back birds, bugs and salmon

Putah Creek is a tributary of the Sacramento River, flowing through the cities of Winters and Davis. It barely flowed at all after Monticello Dam was installed in the 1950s, which created Lake Berryessa and drastically reduced water to Putah Creek.

Then, in 2000, a lawsuit brought about the Putah Creek Accord, which mandated year-round flows to protect fish and habitat. Since then, local community members, nonprofits, state agencies and UC Davis researchers have worked to restore and study the creek. They’ve found that once water returned to the stream, so did insects, songbirds, and eventually, salmon.

Hatchery fish and new wild salmon

Until this study, the hundreds of salmon in Putah Creek were all thought to be hatchery strays.

“People began speculating whether any of these Putah Creek-spawning fish were returning to Putah Creek,” said Rypel, a professor in the UC Davis Wildlife, Fish and Conservation Biology department. “It was a challenging scientific riddle to figure out.”

First author Lauren Hitt, a graduate student in Rypel’s lab during the study, used otoliths — or ear bones — from adult Chinook salmon carcasses recovered from Putah Creek between 2016 and 2021 to determine their origin.

No bigger than a thumbnail, otoliths carry within them the water chemistry of the streams they have traveled, allowing scientists to map their movements and migrations against the chemical tracers of individual streams. This powerful technique allowed Hitt to reconstruct each salmon’s life history. She showed that while hatchery-origin fish were most abundant, a handful — 11 of 407 — of returning salmon analyzed were born in Putah Creek, completing their full life cycle as wild salmon.

This new run of wild salmon at Putah Creek descended from hatchery fish­ — a finding that could upend some long-held perspectives about the role of fish hatcheries in conservation. Hatcheries provide food and a fishing boost for anglers, yet they have often been criticized for impacts to wild fish genetics, health and habitat. 

“The idea that hatcheries can be part of the solution might take people off guard,” Rypel said. “But there may be positive effects so long as the salmon have a good place to go. There’s a lot of potential to have more Putah Creeks out there.”

Local love

Salmon born in Putah Creek face many challenges in completing their life cycle. They must leave Lower Putah Creek, enter the Yolo Bypass floodplain, travel to Liberty Island, down the Sacramento River and into the San Francisco Bay before emptying into the Pacific Ocean. At the end of their life, they get to do this in reverse. Along the way, restricted fish passage, reduced flows, too-warm, too little or too much water at the wrong time can be fatal.

In a sobering illustration of these risks, Putah Creek-origin salmon from 2021 died before being able to spawn because an atmospheric river sent debris and ammonia-saturated waters into Putah Creek just as spawning salmon were beginning to arrive. The authors say such setbacks are significant but not insurmountable provided collaborative management of Putah Creek in the future.

“There’s so much local love for these fish,” said Hitt, currently a Ph.D. student at University of Canterbury in New Zealand. “I hope people recognize that their caring about the system and advocating for the system are what made the changes possible. If not for local community engaged and supporting local streams, I don’t think we’d have salmon in Putah Creek today of hatchery or Putah Creek origin. This is just so special.”

A salmon run at UC Davis

As for UC Davis’ salmon run? Scientists will continue to sample and monitor the fish as they come home. Visitors and community members may see salmon spawning each fall at the Putah Creek Riparian Reserve and throughout the creek.

The study’s additional coauthors include Malte Willmes of Norwegian Institute for Nature Research; Rachel Johnson of National Marine Fisheries Service and UC Davis; and George Whitman, Mackenzie Miner, Carson Jeffres, Dennis Cocherell and Nann Fangue of UC Davis.

The study was funded by the Solano County Water Agency, Yolo Basin Foundation, UC Davis Agricultural Experiment Station, Peter B. Moyle and California Trout Endowment for Coldwater Fish Conservation, and UC Davis Erica Kelly Memorial Award and Jastro-Shields Research Award funds.

Meet the thriving stray dogs of Chernobyl

Sarah Knapton
Mar 04 2023

The nuclear ghost town of Pripyat, 2 kilometres from the Chernobyl Nuclear Power Plant, in a video marking the town's 50th anniversary in 2021.

Living amid the fallout of the world’s worst nuclear disaster may not seem like a sensible lifestyle choice, but the dogs of Chernobyl may have evolved to make it work, a study suggested.

Scientists have found that strays living in the exclusion zone of the Ukrainian disaster have developed distinct DNA and behaviour from other canines.

Since the nuclear catastrophe took place in April 1986, the area surrounding the nuclear power plant has largely been abandoned by humans.

But although radioactive contamination devastated wildlife populations there, some animals survived and continued to breed – including feral dogs, some of whom may have descended from domestic pets.

The team found that the strays had formed into packs, like wild dogs and wolves, but the groups were living close together, a behaviour not seen in undomesticated animals.

The dogs have been monitored by the Chernobyl Dog Research Initiative since 2017, and a new study of blood samples taken by the project team has shown that the animals were genetically different from other canines.

Now the team are planning to study the new genetic traits to see if any of the mutations is helping them to survive in the radiation zone.

Discovering how mammals evolve to live in harsh radiation environments could bring important insights into how to predict
 cancer in humans, or protect astronauts in the deadly radioactive environment of space.

Some animals, including dogs, survived and continued to breed long after Chernobyl was sealed off to humans.


Dr Elaine Ostrander, a geneticist from the National Human Genome Research Institute, part of the US National Institutes of Health (Nih), said: “We don’t yet know what, if any, genetic differences might allow dogs to survive in one versus another environment.

“Looking for changes in the DNA that have helped one versus the other population survive is the long-term goal of the study and one we are working towards now.

“We think that is an important experiment because those changes, if identified, would be helpful for understanding early events in cancer, help guide using therapies for diseases that are motivated by radiation exposure, and would suggest ways in which we can better protect ourselves from both accidental and natural radiation exposure.

“For instance, we know that space is a high radiation environment, and information from this study could help scientists design ideal protection for those spending significant time in space, as space exploration continues to expand.”

Scientists hope that the genetic discovery could offer insights in preventing cancer in humans.

The Chernobyl disaster began on April 26 1986 with the explosion of reactor number four at the nuclear power plant causing an updraft of radioactivity which spread across Europe.

Two people died immediately and 29 within the coming days of acute radiation syndrome, while the United Nations estimated some 4000 more died from the fallout.

Many women also aborted their babies for fear they would be affected by radiation poisoning.


Some 300,000 people were evacuated from their homes and, in the aftermath, a 1600-square kilometre exclusion zone was set up around the site.

DIMITAR DILKOFF/GETTY IMAGES
The stray dogs have been monitored by the Chernobyl Dog Research Initiative since 1997.

However, in recent years, researchers have found that closing off the land to humans has allowed wildlife to flourish, with the area now a haven for lynx, bison, brown bear, wolves, boar and deer as well as 60 rare plant species.

The Chernobyl Exclusion Zone currently represents the third-largest nature reserve in mainland Europe and is often considered an accidental experiment in rewilding.

Previous studies showed that exposure to radiation speeds up the genetic mutation rate among plants, with some species evolving new chemistry that makes them more resistant to radiation damage and protects their DNA.

Scientists have pointed out that in the past when early plants were evolving, levels of natural radiation on Earth were far higher than now, so species may be able to switch on dormant traits to survive.

However, it was unknown whether the same protective adaptations would be seen in larger animals.

The new study was based on 302 free-roaming dogs living in the exclusion zone, which were found to have different genetic make-ups depending on how much radiation they were exposed to.

The Nih team is now planning to study the genetic changes to find out whether they are helping the dogs to survive.

The research was published in the journal Science Advances

The Chernobyl Nuclear Disaster Created Genetically Mutant Dogs

Roughly 350,000 people evacuated during the 1986 disaster at the Chernobyl Nuclear Power Plant in 1986, leaving their lives and belongings behind to flee the worst nuclear disaster in history. Facets of residents’ lives left behind but often unmentioned are their pets, which evacuees were forbidden to retrieve. Despite the high levels of radiation in the Chernobyl Exclusion Zone, many of these animals survived, and their descendants can be found in and around the region today.

Prancer, one of these dogs, got her name from a dance she does whenever she greets Tim Mousseau’s research team. Mousseau, a biology researcher at the University of South Carolina, has studied the effects of radiation on living organisms in sites like Chernobyl and Fukushima for decades. Usually, however, his subjects are a lot smaller, potentially a result of the extremely harsh conditions created by nuclear radiation.

“These are dogs. You can't help but love them and develop relationships with them,” he told The Daily Beast. “We think about bringing them home with us every time we go.”

Dog Genes Hold More Secrets About Humans Than You Think

Even in conditions that drastically limit their lifespan—Mousseau said most of the Chernobyl canines only live to three—the dogs have found a way to thrive. Locals and an increasing number of dark tourists feed the dogs resulting in a surge in the canines’ population that have driven nonprofits and researchers to regularly provide veterinary care, and spay and neuter as many dogs as they can. Over the course of three years, Mousseau has collected hundreds of blood samples from the dogs as part of these efforts.

The dogs’ blood contained an incredibly rare opportunity: a glimpse into how life prevails even under unnaturally harsh conditions. When Mousseau came to National Human Genome Research Institute geneticist Elaine Ostrander to analyze nearly 300 of these blood samples, she wasn’t about to let the chance slip by.

“I said, ‘Me, me, me, me, me,’” she told The Daily Beast. “It's such an extraordinary opportunity, and it does have implications for human health and biology.”

The Mystery of Chernobyl’s Black Frogs

Mousseau and Ostrander’s team published genetic sequencing results from the Chernobyl dogs on March 3 in the journal Science Advances. According to the authors, the study represents “the first genetic analysis of domestic dogs affected by a nuclear disaster,” providing a baseline to measure the impact of prolonged radiation exposure on an animal’s genetic health.

The radiation in Chernobyl City and near the power plant breaks the pooches’ DNA strands. Their cells try to repair it, but errors often occur. DNA gets deleted, spontaneously added, or switched around willy-nilly. Understanding how the Chernobyl dogs are able to survive in spite of this constant assault could inform a field like cancer treatment, since incorrectly repaired DNA is often found in cancer cells, Ostrander said.

“These dogs are surviving generation after generation, they’re fertile, they're carrying out all their bodily functions, and they even have behavioral relationships with people in the area—they're doing all the dog stuff they're supposed to be doing,” Ostrander said. “What's allowed them to overcome [the radiation]? From the viewpoint of someone at the National Institutes of Health, we really care about that.”

During visits to the Exclusion Zone, Mousseau and others have noticed dogs living both in Chernobyl City and in and around the nuclear power plant—the latter of which is striking, given the area’s high, ongoing levels of radioactive contamination. But it was not known how closely these two populations were related, and additionally, how genetically similar they were to dogs in a nearby village.

As it turned out, both were genetically distinct—from a nearby village dog population and from each other. The next step, which the researchers are already diving into, is to start to isolate the genetic regions that make the Chernobyl dogs different. It’s all speculation at the moment, but Mousseau and Ostrandar both have theories.

For his part, Mousseau has studied an assortment of flora and fauna in radiation zones and found that some species of birds have safety mechanisms in their genes that protect them from the worst effects of the radiation. Might the dogs living near the power plant have such molecular failsafes, too?

Now that the researchers have a baseline for these dogs, they are able to isolate genetic differences that aren’t just due to the quirks of the populations. Any disparate finding could improve the dogs’ ability to survive in their environment. For instance, if the Chernobyl dogs have genes encoding shorter fur than others nearby, it might mean they don’t hold onto as much radioactive dust in their coats. Or, if they have more genes relating to processing scents, it might mean the dogs can smell without putting their noses to the radioactive soil.

“In terms of looking at the genome, this is one of the most exciting projects ever,” Ostrander said.

But Russia’s invasion of Ukraine has complicated the research efforts: The last time Mousseau visited the region, the Crimea Bridge was bombed. Currently, his team sends about 800 kilos of food to the dogs every week, and the nonprofit Clean Futures Fund supports on-the-ground care for the animals.

“We hope that this research will shine a light on the situation in Ukraine to a broader audience,” Mousseau said. “We should all be concerned about the care of animals, even if they're stuck in a place like Chernobyl, in a war zone.”

Can the dogs of Chernobyl teach us new tricks on survival?

More than 35 years after the world's worst nuclear accident, the dogs of Chernobyl roam among decaying, abandoned buildings in and around the closed plant – somehow still able to find food, breed and survive.

Scientists hope that studying these dogs can teach humans new tricks about how to live in the harshest, most degraded environments, too.

They published the first of what they hope will be many genetics studies on Friday in the journal Science Advances, focusing on 302 free-roaming dogs living in an officially designated “exclusion zone” around the disaster site. They identified populations whose differing levels of radiation exposure may have made them genetically distinct from one another and other dogs worldwide.

“We've had this golden opportunity” to lay the groundwork for answering a crucial question: “How do you survive in a hostile environment like this for 15 generations?” said geneticist Elaine Ostrander of the National Human Genome Research Institute, one of the study’s many autho

Fellow author Tim Mousseau, professor of biological sciences at the University of South Carolina, said the dogs “provide an incredible tool to look at the impacts of this kind of a setting” on mammals overall.

Chernobyl’s environment is singularly brutal. On April 26, 1986, an explosion and fire at the Ukraine power plant caused radioactive fallout to spew into the atmosphere. Thirty workers were killed in the immediate aftermath while the long-term death toll from radiation poisoning is estimated to eventually number in the thousands.

Researchers say most of the dogs they are studying appear to be descendants of pets that residents were forced to leave behind when they evacuated the area.

Mousseau has been working in the Chernobyl region since the late 1990s and began collecting blood from the dogs around 2017. Some of the dogs live in the power plant, a dystopian, industrial setting. Others are about 9 miles (15 kilometers) or 28 miles (45 kilometers) away.

At first, Ostrander said, they thought the dogs might have intermingled so much over time that they’d be much the same. But through DNA, they could readily identify dogs living in areas of high, low and medium levels of radiation exposure.

“That was a huge milestone for us," said Ostrander. “And what’s surprising is we can even identify families” – about 15 different ones.

Now researchers can begin to look for alterations in the DNA.

“We can compare them and we can say: OK, what’s different, what’s changed, what’s mutated, what’s evolved, what helps you, what hurts you at the DNA level?” Ostrander said. This will involve separating non-consequential DNA changes from purposeful ones.

Scientists said the research could have wide applications, providing insights about how animals and humans can live now and in the future in regions of the world under “continuous environmental assault” – and in the high-radiation environment of space.

Dr. Kari Ekenstedt, a veterinarian who teaches at Purdue University and was not involved in the study, said it's a first step toward answering important questions about how constant exposure to higher levels of radiation affects large mammals. For example, she said, “Is it going to be changing their genomes at a rapid rate?”

Researchers have already started on the follow-up research, which will mean more time with the dogs at the site about 60 miles (100 kilometers) from Kyiv. Mousseau said he and his colleagues were there most recently last October and didn’t see any war-related activity. Mousseau said the team has grown close to some dogs, naming one Prancer because she excitedly prances around when she sees people.

“Even though they’re wild, they still very much enjoy human interaction," he said, “Especially when there’s food involved.”
