IMO you can't beat a full yorkie. They are perfect as is- nothing else required.
I agree with Princessdiana on the other questions. I have 3- one uses potty pads in a litter box, one mostly uses my pool deck

I keep all of mine in puppy cuts but they still go to the groomer once a month. Welcome to YT!
