I agree with everyone else give it time and I am sure Winnie and Tory will be best buddies. I don't think size has anything to do with it. Georgie's deceased sister was a 75lb Boxer and they were BFF's. I think time and nurturing will help the situation all work out. When we had our skin son 5 years ago we made sure Georgie knew he was still important and also gave him his space when he needed it. I think Winnie will be just fine once things settle in. Post some pics would love to see them
