Lately, blue stray dogs have been spotted running around Navi Mumbai, India, and it’s no laughing matter. Inadequate waste treatment at a local river has allowed dye to leach into the water, turning dogs who wade in a bright blue color. To add to the concern, the pollution is likely harming fish and birds who rely on the water resource. Residents began noticing blue dogs roaming the streets and were prompted to bring a complaint to the local authorities, asking that the water pollution be controlled.
