The strays, thought to be former guard dogs, are said to scavenge for food at a tip on the outskirts of Yekaterinburg city.A local resident said he thought someone was playing a practical joke when he saw the hounds in the snow.
"I go past those dogs every day," Alexei Bukharovsky said.
"They are usually reddish... but then I saw, running along the white snow, an almost completely emerald dog."
A police spokesman told local news service RIA Novosti that it is thought to be the result of illegal tipping.
"Either local residents or a factory have been dumping some kind of chemical waste there," the spokesman said.
The council has been asked to clean up the site.
