I'm with Rachelsyorkie---I though I had the most aggressive dog ever and when leaving (and praying) him at the Petshotel or at the groomers I was very aprehensive. However, when he is away from his family the reports I get are he is the sweetest little dog ever--who LOVES to play with other dogs. At first I thought they had the wrong dog but as I see it, he doesn't have to worry about protecting me from others when I'm not around. Sadly, that doesn't deal with those who come around when I AM with him, but we are working on this. Good luck!
