He got sausage, he loves sausage. I keep sausage for training and walks only, never just as a little treat. It might be some time before he does it again, but I work on the theory and hope that if he's done it once, he'll do it again.If he does stop when asked, make sure you give him a huge jackpot treat as a reward because that really is quite impressive - he's showing self-control and it's not a skill that comes naturally.
