The dogs in Dzerzhinsk are take care more like Smurfs than cuspid .

If you ’ve been on Pet Internet this week , you ’ve probably seenthe blue dogs in the Russian town of Dzerzhinsk .

There was apprehensible worry about the bow-wow , but Reuters report that the dogs are in " normal " status at a local clinic . So what caused the isolated dogs to ferment blue ? We do n’t for certain , but there ’s a good fortune it was because of a very normal dog conduct : roll in something they should n’t have .

Here ’s the hypothesis of Paul Amerling , DVM , who has 25 year of clinical experience : There ’s an abandoned chemical plant near Dzerzhinsk , which , according to one Russian functionary , still may contain copper sulphate . Take a look atwhat that can look likewhen it ’s ground into a powder . Seems passably like to the dogs ' new colouring , no ? peradventure they just rolled in it . That would excuse how their hair’s-breadth looks .

" The frank are sort of patchy blue , " says Amerling , who has never seen blue dogs in his decades of fauna medicine . " Certainly not consistent . "

The isolated frank probably did n’t plow drear from eat the copper color sulfate either , he says . He even contact his former toxicology prof , who told him that ingesting too much copper can only make pelt darker — not ferment it blue .

Now , the dogs eating the copper sulfate would still be problematic because excessive fuzz can alsodamage a dog ’s liver and digestive systemand maybe lead in death . So it ’s no surprise Humane Society International ’s Vice President Kelly O’Meara , who spoke withNewsweek , is worried about the andiron .

" The dye on their fur implies they have had unmediated contact with or even uptake of potentially toxic or harmful substances . This could result in painful peel cut or itching or internal hemorrhage and illness that could run to last , without veterinary intervention , " she said .

A spokesperson for the Russian government state the land ’s media that officials are in talks to find the sources of the aristocratical coloring and ensure all the dogs are hunky-dory .
