Stray dogs with bright blue fur have been spotted roaming the streets near an abandoned chemical plant in the Russian city of Dzerzhinsk, about 230 miles east of Moscow.
The factory went bankrupt in 2015 and produced plexiglass and hydrocyancic acid, which hydrogen cyanide dissolved in water.
The dogs’ fur may have been dyed by chemicals including copper sulphate, a bright blue inorganic compound used in a number of industrial process.
It’s still unclear what the exact cause of the blue fur is, but it’s bad news for the wellness of the poor dogs regardless.
The dye on their fur implies they have had direct contact with or even ingestion of potentially toxic or harmful substances. This could result in painful skin burning or itching or internal bleeding and illness that could lead to death, without veterinary intervention.
City officials have taken the dogs to a veterinarian nearby to have them tested.
