Bella & Harley are outdoors trained.
My reason is...I don't want dirty potty pads in my home, they smell and they are nasty IMO...Now if I lived where it snowed and just to cold to go out I probably would consider them but, I live in South Florida, there is no snow and it hardly ever gets below 30 here in the winter so I see no need for them...My babies come to work with me so they are hardly ever home alone for more than 4 hours at a time. Harley is confined in his play yard for his safety and with a potty pad just incase of a accident, he's only 5 1/2 mos old, if I know I will be gone longer like 8 hours or more..my BFF has a Yorkie too and she fursits for us.
