If fights only happen when leash is on them, it might be either you and your friend were tugging the leash or sending a nervous energy to the leash. That could start the fight. Be sure that the leash is always loose, very loose otherwise it could send a wrong message to your dog. Sometimes, you are not aware that you are doing it. I have seen a lot of people tightening up their leashes without knowing it when introducing their dogs. That is a big no-no to me. That is why in some situation dogs get along better when introduced without a leash. |
