Ok... my two year old Cairn has a bit of a problem. Whenever he can get a chance, he will eat my other dog's feces. She (my other dog) goes #2 on the side yard because we can't always walk her..and if we let our Cairn out before we clean it up, he will try to eat it. We almost always clean it up before he can get a chance to,but sometimes we forget. I know that puppies tend to do this, but he is 2 and I think he should be over it by now. We've tried many different things..so far the only thing that works is cleaning it up before he gets to it...but I just don't think this should even be an issue. Why does he do this and what can we do to make him stop?!
