When we want to play with her she starts biting us or something else.
Hi Mayra All puppies bite to some degree, it's a very normal puppy behavior and a big part of the way they interact with other puppies and dogs.
However, it's never okay for a pup to think that biting humans is allowed, and it needs to be discouraged from day one. Often pups bite and nip at children more than adults because they see them as 'siblings' (ie other puppies) rather than figures or superiority.
My Puppy Biting page has lots of tips and advice on dealing with this behavior, and if you follow the guidelines there you should be able to put an end to this problem. Remember though, your puppy is a baby, and it takes time, love and patience to help her learn the correct way to behave.
