phillipp we're absolutely committed to sorting the problem. It took us several years to sort one of our pets out so that he can wander freely without any harm to himself or anyone else, and months to help a cat that had been so maltreated it was bordering on feral. Both are much loved family pets now, and I know with a bit of love, attention and the right training, we can get there with this puppy as well. We have the time, and if it takes it, the money to get whatever help he needs.
He is a lovely, lovely chap when he's calm - its just he goes from calm (able to be stroked, will play with a toy) to crazy (cannonball with teeth) with no warning. Classic case of no social skills.
Trionic will try council/HMRC/KC route as well. The vet told us the reason she was trying to offload these pups so cheaply is because she'd tried to sell them as working dogs, but all the vets round here refused to dock their tails because they were so concerned about how she was breeding her dogs. So she's well known for poor form.
The back turning on the biting isn't doing brilliantly - he just bites my backside instead. Admittedly, it's quite an ample arse, but I'm quite fond of it, and would prefer not to lose any of it to his bite.
What seemed to work better today was the "petting/rewarding" approach - he seems to like that, and it at least makes him feel safe. You can see that in his eyes.
This isn't a dreadful dog beyond salvation. When he's happy and calm, you can see the dog he has the potential to be. He just needs some help getting there, and he definitely needs it through a really positive reinforcement approach. Anything more archaic is likely to result in some serious aggression, I suspect.
I'll get onto some of the behaviourists on Tuesday - the sooner the better. DD's back at school in a couple of weeks, and the horses go back to the yard, so it will be easier to work with puppy then.
Has anyone ever used a residential "bootcamp" approach? It doesn't feel right to me, but our neighbour does it for all her dogs (5 and counting) with a great deal of success.
