Mysterious Blue Dogs Appear Outside Old, Abandoned Chemical Factory

Something very strange was recently discovered near an old, abandoned chemical plant in Russia: a pack of stray dogs covered in blue fur.

The Dzerzhinskoye Orgsteklo plant, which once made hydrocyanic acid and plexiglass, closed down several years ago — but the building still stands.

People who live near the plant began spotting the blue dogs wandering around outside the structure. They shared photos of the mysterious pups online, in an effort to alert local authorities.

The dogs were eventually caught, and they're now staying at a vet clinic before going up for adoption. They're said to be eating and drinking normally, and their blood tests came back normal.

Watch the video below to see what scientists believe has caused these dogs to turn blue.
