The whole time we have had Buster, he has always had to go and smell the other dogs butts while they are doing their business. Sammie has gotten so irritated by this that she has tried to go in the neighbor's yard away from Buster to go pee and poo. Buster was sniffing Luna's butt while she was doing her business, and Luna still has soft stools. Buster got his head pooped on and it stunk to high heaven. And, of course, Buster does not like baths. I tied him to our clothes line outside and hosed his head off the best I could. I was not going to bring him in the house like that. Then he got a bath after we got in.
BTW. Buster used the cat's litterbox again. I caught him when he was almost done and didn't get the camara until after he was out of the litterbox. Since he has started doing that, we haven't found any accidents anywhere. He still goes outdoors though. I wonder how he figured out how to do that. We didn't train him to go in the cat's litterbox. Seeing as how he is a Saint Bernard, I didn't think it was possible for his lardass to fit. Now if we can just get him to do the things we are actually training him to do.
