We rescued a lovely border collie three months ago (had collies before so have a good idea of the breed) although never had one who's such a nightmare on the leash. In all other ways he's an idyllic dog, so good with the kids and mega affectionate. On the leash though he shows fear towards other dogs by agression, he goes manic when faced with one, he even managed to catch my dh leg with his teeth the other day during an episode. We are gonna work on sorting this behaviour out but were wondering do you think we would be able to introduce another collie into the family home?. Theres a female who's 2 like him who needs homing and we were wondering if its poss they could get along if conditions were controlled on being introduced and wondering if having a friend would help him? am I kidding myself that its even possible?
