That wet stuff coming out of your dog's mouth? That's saliva, better known as drool. And it's a normal function of most dogs. In Why Do Dogs Drool?, children's author Sally J. Labadie explains all about drool and why it happens.

Offering a humorous, but factual look, at a dog's drool, this picture book helps kids understand their dogs, and it also gives them information about what to watch for in case of issues. But most importantly, it encourages kids to love their pets no matter what.
