Surviving the hot weather

Lately our fluffy poodle can often be found sleeping on her back. To the naked eye this must look like a poodle who has no sense of danger, exposing all the vulnerable regions of her body. However, what she is really doing is trying to lose more heat. I'm not sure how effective this is, but I'm so happy that Brie is not overheating. Because I am melting in this heat.
