A pack of bright blue dogs appeared and went viral

Why are dogs blue?

The dogs are said to have acquired this color after being exposed to chemicals at an abandoned factory nearby, according to initial reports. The factory produced plexiglass and hydrocyanic acid, but it closed six years ago after going bankrupt.

The hydrocyanic acid, a suspension of hydrogen cyanide in water, was originally isolated from the Prussian blue pigment and takes its name from cyan, the ancient Greek word for blue.

The Center for Disease Control and Prevention describes it as toxic and its uses range from a commercial dye to an element in a chemical weapon.

The former director of the chemical plant bankruptcy, Andrey Mislivetshe told the state news agency RIA Novosti that the factory buildings also store copper sulfate, a chemical known for its bright blue color. “Stray dogs are roaming the land, they may have found the remains of old chemicals and rolled around in it, and maybe it was copper sulfate.” detailed in the middle.

Deceptions reported that several years ago something similar happened with animals that changed color after coming into contact with artificial dyes.

RIA Novosti also reported that animal rights agencies have said the dogs’ health is unlikely to be at risk.
