I have a 9 week old pit bull puppy. He is teething for the first time. I have given him chew toys but if someone goes to pet him he will bit them and try to chew on their hand. It was a cute thing for awhile but it's starting to actually hurt and break skin. How can I train him to stop biting people? Is there anything else I can do besides chew toys that can help him?
When he nips, shout "ow! no!" a bit louder and sooner than necessary, and if necessary stop playing and walk away. That's how dogs teach each other not to nip, after all -- they growl or bark and don't play with the annoying one until he learns not to be so rough.
"Pit bulls" should be as capable of being gentle/careful as any other dog. But a puppy is a baby; as surrogate parent, it's your job to teach him how to be a Good Dog.
Oh -- and give the pup some good chew-toys.
