In a Mumbai, India suburb, some stray dogs are turning blue. It may be due to untreated industrial waste dumped into the Kasadi river, which dogs sometimes wade into to look for food. The surrounding area has close to 1,000 pharmaceutical, engineering, and food factories, and the polluted water is likely affecting human health as well.
"It was shocking to see how the dog's white fur had turned completely blue," said Arati Chauhan, who runs an animal protection cell. Chauhan has spotted around five such dogs and has asked the pollution control board to act against the polluting industries," the Hindustan Times reported.
