Yes Pnance, thank you for your advice and help. It does make sense but it is just very sad.
Duncan is just like the dog in your story, except I don't use a pinch collar on him. He cannot be around anyone but me really. Not even Collin. It makes me sad that he will never have any friends or be able to play freely.
I have to muzzle him when company comes over also, just to be safe. I hate it because I know how sweet he really is and having the muzzle on just sets him apart even more... But I understand that in order for him to stay alive, I have to be cautious in every situation.
It just makes me sad and upset and I always think that maybe there is hope for him, maybe I'm the problem, would he be happier if I did something different...you know?

Anyway, welcome to Pet Talk!!
