Lefty eats poop--he seems to have a preference for dried out cat poop. I am REALLY trying to get him to stop, but it seems like I'm spending a lot of time saying "Leave it!" I've heard that this is a hard habit to break; I guess his former owners didn't work on it much with him. It's a little hard to believe that I can give him dog food he really seems to enjoy, but yet he'll tug and tug at the leash to get at a piece of cat poop...
