People say dogs mark their territory when they pee? I hear another person say they don't have the concept of territory. "A dog doesn't know the difference between his yard and the neighbors yard if it weren't for the fence between them. This person says that dog pee because they are nervous. That once they move out of their place of comfort they get nervous and pee because the want a sense of familarity, so they make everything smell like them. What do you guys think about this one? I never thought about it that way. It's something to think about. Challenge YOUR Life!
