I have my share of skin abrasions from those puppy teeth, but shes on her original toys from a pup and shes 5 months, she hasnt destroyed anything? I just played catch with her with an egg, she caught it and ran around with me chasing twice, the 3rd catch her tooth popped it. Im sure my shutz trainer wouldnt like it, shes been teething so I cant work on her bite yet.
