So, can the tail wag the dog???

I know you are really curious about this. So, I thought I would throw in my opinions.
The people in my house say I get really, really excited about going on a walk. When I see them get my leash, it's all good in my opinion. It means we are either going for a walk, or a ride, or just outside. There isn't a down side with seeing the leash in someone's hands around here.

But anyway, they make me "sit" before they will put the leash on. They say that since my tail gets so excited, that YES, the tail can wag the dog.
