It's good to hear that some yorkies love to swim. We have a pool but it's yet to be warm enough. So much for sunny cal. I will put him in the pool just to make sure he can swim if he fell in. My Chupa(chihauhua) can swim but hates the pool. Soda(Pitbull) loves it in the summer. Even jumps off the diving board(allthough she's getting a bit old for that now). One day it will warm again. (I hope)
