You need to insist. You also need to stop caring what other people may think of you, for that moment, because otherwise you won't have the consistency needed to ensure that Tobias learns proper bite inhibition with humans. What is more important to you, right now: what a child, or a stranger thinks of you (Oh my god! I just wanted to pet her puppy, she's such an X!) or that your puppy grows up to be a wonderful companion around human and animal alike? It is a tough call and as someone who had loads of social anxiety and depression, getting the gall to tell people a flat and blunt NO was very difficult. But I had to, for my dog's well-being.
Tell your parents in a straight forward, matter-of-factly way that they need to engage with Tobias in a certain way until he's learned what he needs to, in his puppyhood. Ask if they would enjoy having a full-grown, 15kg+ dog with developed adult teeth doing the same nipping and gnawing. Probably not.
When strangers try to pick him up or smother him, you need to step in. Ace is a rather unusual colour for the dogs out here and as a result, when he was a puppy, he had loads of people wanting to hug him and hold him in their arms. He was terrified, of course, at some random person swooping down and lifting him away from his mum. If they do it incorrectly, it can also be physically uncomfortable for the dog. Just insist. "Tobias needs to keep his four feet on the ground, but you're free to pet him like this" and then show them how to approach your puppy to set everyone up for success.
Very young children and toddlers are usually bad news for puppies (particularly in their fear periods) if they have not been briefed by an adult on how to say hello to dogs. What I found usually works is asking the child to sit down on the ground, and letting the puppy come up to them to say Hi. This ensures the child cannot move freely, and won't be able to kick at or stagger towards the dog in a way that could be perceived as scary.
At 9 weeks old he probably doesn't even know what "no" means yet. I would not allow other people to rough house with him, and I would monitor interactions with other people very carefully. If people ask to pet him, get down on his level and hold the leash near his collar - any biting and he should get a sharp verbal correction and move him away from the person immediately. I wouldn't rely on other people to do the correcting for you as most people won't.
He's a bit young for NILF as that really requires him to at least have a solid sit or down IMO. What worked the best to curb biting with our pups was a sharp NO! and then immediately turn your back and ignore them. Walk away if needed. If they persist with being naughty, a stern TIME OUT! and 5-10 minutes alone in a puppy safe room to cool down usually works wonders. Heck mine are 3 and 4 and still act like perfect angels when threatened with the dreaded time out, lol.
He bites, you give a sharp "no!" and ignore/walk away from him. As fr other people, I had the same problem when Lemmy was a puppy. You need to be very firm, and don't be afraid to physically remove him from other people, just be like " He's getting to worked up" and if you get the " Hes a puppy it's fine" just explain " no, he needs to learn proper people skills" and leave it at that.
I hated "being mean" to people, especially strangers, but It's better to be "mean" then have to fight for your dogs life, ebcause some....dummy, claims the dog "viciously bit" them.
Exactly! I drove me nuts, even now, that both my dogs are full grown, random strangers think it's ok to reach out and pet my dogs without even saying a dang word to me! It's an unfortunate side effect of having a corgi, they're inviting looking lol.
A lot of great advice here. 9 weeks is really young and he is a work in progress so continue to be patient. I had great luck with a very consistent high pitched dramatic sqreech if teeth touched my skin. As for the other people I am afraid that now is when you must start protecting your dog. If he does not learn not to bite, as he grows older it will become a problem and the same person that rough houses or allows nipping now will hold you and your dog accountable when he is older. I don't think it is fair that every dog bite is legally considered the dog's fault but it is and as owners we have to train our dogs with that in mind. These days pass quickly so enjoy as much as you can!
What you are quickly finding out is that it's harder to train people than dogs! :-D
If someone walks up to pet him, tell them firmly: "Wait a minute". Then slip the leash under the arch of your shoe, leaving him room to stand, but not jump. Then tell the person. "He's in training. He gets very excited and has to learn not to bite, could you gently pet him only on the body, not the head?" If they start saying "Oh, I don't mind" reply "But I do!, can you help him learn the calm way to greet people, so he does not bite anyone else? I don't want to have to scold him. " ( Don't rush through this part, it will slow down the person as well as allow the puppy a little bit of time to settle ). Most people will comply if you ask for their help, but you need to really get them to stop and get their attention first. Keep things low key, the more the pup gets excited, the more he will not be able to cooperate. If you think the person cannot or will not do what you are asking, scoop up your pup and say, "Sorry, my pup can't handle this yet, we'll keep working on it." and leave.
Don't let ANYONE pick up your puppy. Pups can wiggle out of people's arms and hurt legs or necks or backs in the fall.
If children come up, again use a quick "wait a minute" Then ask them to come up one at a time. Even young children ( 4yrs. old and over) will follow directions nicely one at a time. Younger than 4, with a pup so young, tell the parents it's not safe yet to let them pet the puppy. Place your hand on the side of his head that is towards the child petting him, so the child only has access to the body.
Be clear about what you want from each interaction. Each interaction is a great training opportunity and is free!!! As for your parents, try having a relaxed conversation with them without the puppy being around, so they can take in what you say without that distraction. Don't criticize their ways or their dog. Just stick to your guns and be clear about what you want with your own. Rough housing will always work against you whether it's with your Dad or your boyfriend.....
