Mack is 10 weeks old today and he is a fireball. I cant even pet him unless he is biting my hand. He even barks and growls when i tell him no or get on to him. Any suggestions for how i need to go about breaking him from biting so hard? The breeder i got him from told us to thump his nose and say no loud. Let me tell you i would like to see her personally do it. It only took us 1 time and I'm not attempting it again. He literally tried to take off my hand. We have been telling him no when he does it and offering chew toys and such, but he is still a handfull. Do you think he will eventually grow out of it, i sure hope so. I know puppies will play and chew , but i have young children and im scared he may bite them too hard. Please respond if you have any suggestions besides poppin his nose lol...
