I'm trying to work out whether stagnant drinking water is harmful to dogs (and other pets). I'm talking about the type of water that is just left sitting in bowls/buckets/puddles to the point where it attracts green algae.
Does anyone know whether algae affects the quality of the water and if it is potentially harmful to pets?
Would you leave your dog's drinking water for so long that the container began to grow algae?
Thanks very much
