I have found that pups will treat your withdrawal aws a chase game. when he nips you snatch the hand away, and he gives chase.
I have found that when a pup mouths if you press on the tongue with your thumb, even slightly with your nail, that he will let go. then continue to stroke the side of his mout, saying gently.
With older bigger more persistent pups I have found balling up my fist and pushing it further into their mouth which again will cause them to gag, works quite well. If they find having your hand in their mouth unpleasant then they won't want it there.
With my own pups I used to deliberately get them a little excited when small and rolled on their backs, and when they went to bite at my hand I would put their own paw or hind foot intheir mouths. when they bit on their own foot it hurt and they learnt to be more gentle. this was at the baby stage.
With a pup who thought mouthing was a great game, and if you got physical just liked the game even more. I used a blast of water from a spray bottle in their face, and then the No command. My breed isn't a water lover, but even with a freinds Retriever this method worked for undesirable behaviour, but it has to get them full in the face/eyes!
The dingle most important thing is to stay clam, ad keep your movements slow and deliberate to minimise excitement. Small children with their high voices and quick movements are the most exciting playthings of all. That is how the pup is viewingyou all as it's personal playthings Chew toys.
Did you see him with his Mum, how diod she tell him off??? We can learn a lot from canine Mums, and it is one of the reasons I do not subscribe to theearly homing (6 to 8 weeks) theory. It is great for knowledgeable trainers like Guide dogs for the blind who want the pup inporinted on Humans more, but in my Opinion a Pup learns a lot about discipline from it's mother from 6 to 8 weeks.
I think many peopl who have had a litter feel that at around five weeks the bitch is weaning her litter, and doesn't want to be around them, they then split them up, as Mum has had enough.
In my experience and circumstances, where all the dogs interact as a family with the litter, I have found Mum wants to keep contact to a minimum at 5 to 6 weeks, as she is weaning them. Once they6 have accepted that the milk bar is no longer a free for all, she usually begins to take renewed interest in them. Playing with and encouraging them, then knocking them back, and if they squeal, or are overawed, then she encourages them again. the ones that are little so and so's she soon sends about their business, and will refuse to interact with them until they are more respectful.
The pups that I have had from younger generation new exactly what they could do with each dog in the household. They were bravest with Mum, then Grandma they just knew to leave alone, even though she never did more than give a low growl (but she is the top bitch). Half sister mothered them at first, but after ignored them, and gave them a hard stare if they annoyed. Young neice was actually intimidated by them, even though she is the most confident 9over confident) of dogs.
I have never had a problem with playbiting in a puppuy that I have raised from the nest, as I have never tolerated it.
