I want to add my 2-cents worth. Alphie my rescue yorkie once live with a lady who had a pit-bull. In the house and Alphie was always bitting him showing who was Olfa. Well she did not want to take a risk. She got rid Alphie. Gave him to someone who could not take care of him and a abusive husband. So with all of that I have Alphie who is loved Very much and has had his teeth cleaned gone to vet. Gone to groomer and sleeps with me and Jack. (other yorkie).
Runs all day and plays outside and inside.
Well that is all I wanted to say.
Good Luck
Cheryl
