It is so funny when the black lab-rottweiler mix next door starts barking and Rowdy will CHARGE out the doggie door and run full speed to about 3 feet from the fence, barking all the way. Then he stops abruptly and his rear end almost goes over the top of his head!

He just acts like he's running out to tell Oso (lab/rotty) off, but at the last moment, he thinks better of it.
He is also so funny when he gets hold of something he thinks he is not supposed to have (and usually he is correct, he is not supposed to have it) and he runs at a dead run to the doggie door and goes outside. We used to run out and chase him around to get it, but we have discovered if we just sit tight, he will come right back in with it in his mouth. He has a jillion toys laying around that he plays with but he NEVER takes them outside, just the things he knows/thinks we will take away from him.
