@yodabasenji said in biting..again:
I do understand that he can bite while playing if he gets over excited, but for instance, yesterday he was completely calm and went (by himself, she didn't force him of whatever) to my sister's lap for a cuddle and brought with him a chewing toy. And there he was chewing on the toy and my sister was petting him and everything seemed nice and calm for 5 mins and then suddenly he just turned and started biting.
Has anyone ever mentioned that Basenjis have cat-like traits?
Seriously, I think he isn't really clear on what the "rules" are. It is more difficult when multiple people are involved, because it is hard to be consistent and that can be confusing to a pup. You are correct when you mention that rewarding with food treats when he settles could be misinterpreted. You have to be careful not to be sending mixed signals, and there is even a training method called "chaining", where one action leads to the next and the reward comes after the second action. If biting becomes associated with getting treats, you have inadvertently reinforced the behaviour.
I am wondering how old you and your sister are? And whether you have any previous experience training dogs?
RE: restraint. I tend to use a "bear hug" with a small dog or pup, just put your arms around them, no tighter than necessary to maintain control. Be careful of where your face is if the pup should bite and try to control his head. If he does manage to bite your hand, do not let go! It sends the wrong message. Let him go as soon as he quits struggling. That is reward enough. You might verbally praise him for settling down, but I would skip the food reward, and if he starts up with the biting again, you repeat the restraint. He will figure it out.
It will be necessary to restrain your pup when at the vet, so it's good for him to get used to it. Also, there should be no places on his body that you cannot touch or handle. This is important for basic grooming and imperative if he is ever injured and you need to help him.
Exposure to other dogs should help with his manners, and as he is quite young at this point he will likely have "puppy immunity". Adults may put a pup in his place but they seldom get rough enough to injure him. That said, the owner of the other dog needs to monitor in case things get out of hand.
Good trainers are observant and learn to spot signs of trouble before it occurs. If you see him getting restless or showing signs of boredom or aggression, try to redirect his attention to something else. If play consistently leads to biting issues, then that type of play should be off the table for now.
He will likely grow out of the nippy stage fairly soon, and things will get better as you get to know each other and build trust.
Edited to add, if you haven't investigated clicker training, you might want to do that. It works well for teaching new behaviours, and is excellent to train your pup to go into his crate on command, to go to a place (such as a mat) when asked, and many more useful things. Lots of info on line. Karen Pryor is a good resource.
