RE: my dog bit my daughter...
Jackie,
This is going to explode into something much bigger. You need to contact your breeder. You have a young pup and a young child. You should have an older dog (kid proofed) or wait until you child is older and has learned when to pet and not to pet.
Roxie is obviously alpha over your child which is not to be permitted. What are you going to do the next time this happens and God forbid it's your kids face and Roxie has another 10# on her. IT'S NOT GOING TO BE PRETTY. Roxie needs to be with home without small children. It's not fair to the kid or the dog. SEND HER BACK TO THE BREEDER.
