Hi everyone! Well, what we did was positive reinforcement when he did'nt widdle around the house, and so far it seems to be working better than any negative reinforcement we'd been trying. The thing is, he knows when he's been a bad boy because it shows in his behaviour - he gets awfully "shifty"and won't come when he's called. So we tried to give him the fuss when he was a good boy and now he doesn't seem to do it as often. But I suspect the last groomer we sent him to must have hurt him, because he won't let us shower or comb him (and this is really difficult, since he's a shi-tzu), and this has never happened till about 4mths ago, the last time he was sent to a grooming shop. Unfortunately, this has also been around the time when we got the kitten, so we're still trying to figure out if it's the kitty or us or the groomer..sigh.
