I have a 17 month old male Feist with a nippin and jumpin issue. He like to nip at ur hands and feet and ears and pretty much anythin he can get his mouth around. I was wonderin if anyone knew of a way to stop the habbit. I hate hittin him but sometimes he bites really hard and I just can't stop myself, plus he doesn't seem to learn because after I smack his snout, he goes right back to tryin to bite so I know that won't work. We got him from a rescue, so we didn't have him as a puppy. There are a few things I want to teach him, but I need to stop this bitin. I have a 4 yr old son and a 7 month old daughter that I don't want to see hurt because he thinks they are tryin to play with him.
