Mystery as ‘blue dogs’ spotted roaming as experts are baffled – ‘weren’t blue last week’ | World | News
Caregivers looking after stray dogs living around Chernobyl made a surprising discovery; many of the animals suddenly turned blue. The Chernobyl Dogs group, which cares for hundreds of dogs in Ukraine’s radioactive exclusion zone, shared a video showing packs of patched animals and, in some cases, bright blue fur coats; This situation stunned the experts. “We’re not sure exactly what happened,” the team admitted.
“They weren’t blue last week. We don’t know why and we’re trying to catch them to find out what happened,” the team wrote alongside the images. “They’re probably getting into some kind of chemical.” The organization provides food and medical care to the animals every year. These dogs are descendants of pets left behind as residents fled after the 1986 Chernobyl nuclear disaster, one of the most devastating nuclear accidents in history.
Despite the alarming coloring, the organisation, which is part of the Clean Future Fund, reassured followers that the dogs appeared “very active and healthy”.
Social media users were quick to speculate about the sudden color change. “This blue-tinged fur is probably due to external chemical contamination, which can be washed,” one TikTok commenter wrote.
Another said: “I’m surprised these dogs are still fertile after living close to pollution for so many years.”
While blue dogs remain a mystery, scientists have long studied how animals in the Chernobyl zone adapted to the harsh conditions.
An explosion at the Chernobyl Nuclear Power Plant in northern Ukraine in 1986 released large amounts of radioactive material into the environment, causing the evacuation of nearby towns and creating the so-called Chernobyl Exclusion Zone (CEZ). In the absence of humans, wildlife thrived despite radiation levels nearly six times higher than those considered safe for humans.
Recent research suggests that some of these animals have evolved to survive in a toxic environment. A 2024 study found that Chernobyl dogs had developed unique genetic traits that made them unusually resistant to radiation, heavy metals, and pollution.
Researchers from Columbia University, led by environmental health scientist Norman J Kleiman, analyzed blood samples from 116 semi-feral dogs living near the facility and in the city of Chernobyl. Their findings revealed two genetically distinct dog populations unlike any other; This suggests that exposure over generations may have triggered permanent genetic adaptations.
“Somehow two small dog populations managed to survive in this highly toxic environment,” Mr. Kleiman said. “We are taking the first steps to understand how chronic exposure to multiple environmental hazards may have affected these populations.”
