Yes, it happened a couple summers ago. Not all algae is toxic, but there was a toxic bloom in the lake the dog was in.

I clean my dogs inside & outside water bowls every few days. They certainly don't seem to mind drinking from puddles after a rain, but I try to prevent them from drinking puddles in streets when we're walking, I figure they are full of gas & oil runoff from the road..
