As a puppy, every time you feed the puppy, pet his face, and have your hands close to his food. Doing this will ensure that he grows up knowing that a hand near him when feeding or going near his food is nothing to be worried about, and then you won't have to worry about him biting a kid because the kid got too close to his face. Have specific chew toys for a puppy. They will be teething and need to chew on something, so make sure it is something that you won't mind him chewing on. They like ice chips/cubes. If you make some bone broth and freeze it (no onions or other things that will upset his stomach), you can drop a block of it into his bowl and he'll chew on that for a while, get nutritious food and chill his sore gums as those babu teeth break through. If he bites someone because he is teething, yelp like a puppy would if it was hurt. That is dog code for "I'm hurt, stop biting" and they will. You can use it for inanimate objects as well, but you need to also establish your dominance over the dog or he'll think you are a bitcb. Get the kids involved in the daily walks and picking up the shit, fiving the dog baths and feeding him. Make sure the kids dedicate time to playing with the dog every day, and you'll end up with a loving dog, and kids who will know how to care for someone thay they love.
