We have a schnauzer female puppy 8 weeks old she is very sweet except biting. We play with her but she jumps on you and loves to bite.
Hi Barbara Don't worry, this is perfectly normal behavior. All puppies bite to some extent, it's how they play with their littermates. However, you do need to make sure that she learns that biting people is not okay.
It's generally an attention-seeking behavior, and happens when your puppy gets excited (like during playtime). I'd suggest that you read my Puppy Biting page as it has tons of tips and advice on dealing with this behavior.
If you're patient and consistent in correcting her and follow the suggestions on the above page, you will be able to stop this 'nippy-ness'.
