The leash works okay.. there's plenty of slack in it and I'm a fairly light sleeper, don't toss and turn too much. But potty training is all about making sure there are limited chances for accidents. I can't take the chance of him finding a corner he likes in the middle of the night that I don't find out about. As soon as I can trust that he'll stay in the bed, we'll be fine. It's how I trained my Shi Tzu. And since Coby turned 6 months and was nuetered, he is
soooo cuddly. So although we were supposed to wait until potty training was completed, I couldn't wait any longer. Hard thing to believe was that my husband agreed!!
