Princess went out several times a day to potty until sub-zero wind chills this winter when she'd walk on 3 legs or just sit & shiver after about one minute.
So then I decided to try pad training. She's in the house to potty but I try to take her out several times a week even if it's just to take the garbage out or get mail so she can sniff around for a few minutes. She can also go on the balcony rain, snow or shine if she wants.
This summer we'll be at my parent's with a fenced in yard a lot, as well as more consistent walking (I hope!). She loves it outside & there's no way I could keep her in, but to each their own, we're not all the same just as our yorkies aren't!
