This not about a Yorkie but I thought you all might have a little advice. My sister has a Shih Tzu that is 10 weeks old. It has a big attitude. The vet came out and told her today that she needed to get the dog under control and it is going to be a biter.

This puppy is just 10 weeks old. I am in shock. The dog has bit my niece 2 times already. Once in the face once on the arm. I keep thinking maybe where she is only 3 maybe she is hurting the puppy. Now I don't know what to think.
How do you deal with an agressive puppy?
Any advice please. She is almost ready to get rid of the puppy.
