Animal protection groups in India said stray dogs that have turned up bearing bright blue fur were likely affected by pollution in a nearby river. The Navi Mumbai Animal Protection Cell said it has filed a complaint with the Maharashtra Pollution Control Board after several stray dogs in Navi Mumbai's Taloja industrial area were caught on camera with their fur dyed bright blue, UPI reported. The group said the blue color comes from dyes pumped into Kasadi River by nearby factories. The Maharashtra Pollution Control Board said it is illegal for any dyes to be released into the water and an investigation has been opened into the unusual canine hues.
