We have a ten week old chihuahua. She bites us. We use the words "BE NICE" and she cries, we have a lot of toys for her to play with and bite on. she did not get her second set of teeth yet and she is always trying to chew on our hands when we hold her.
She starting to understand the words"BE NICE" when she starts to chew on our hands. We bought her a bed for $12. and she likes to chew on it too. She sometimes settled down and curls up inside it and goes to sleep for awhile.
However, she snuggles between us in our bed at night time. she is so little that we don't mine.
