It's great to hear about your successful potty training! Especially since Yorkies seem to have a pretty bad rep when it comes to that. Mine is 5 months old and also doing great. Can't trust him completely but he sits by the door when he has to go out. If he has an accident it's usually because he was playing hard and all of a sudden has to go. Then it's like: 'oops, too late! Sorry, mom!' But, hey.....they're still learning, right? Good luck with your little angel and welcome to YT!!
