Hi,
I love it when they have a playmate! It must be so cute watching them play together. I've been trying to slowly introduce my rabbits to my pups so no one gets hurt. Anyway, back to your baby..Congratulations! Also, a Yorkie is too tiny to be left outdoors for any length of time. They do have the cutest coats for the days that are very cold during potty runs. Just be careful to keep them dry because a wet cold coat is worse than no coat at all
Good luck and glad you're here!!
