[Critter]

we currently have 2 yorkies, they are such great boys. My husband has been looking into adopting a pitbull and we think we have found one. She has a great personality and has even been around yorkies with her current foster placement. Anyone out there have this type of breed with your yorkie. I am worried about the size difference and of course the "history" of the pit and what they have been known to do. The lady currently fostering says she hasn't seen any aggression and has had her for 6 months. Is there anything I should be considering??
