Agree with Crating-absolutely parmamount for the dogs safety and your sanity. Kongs,Nylabone,and rope floss bones are great-as are raw marrow bones-DO NOT ever give your puppy rawhide or pigs ears-both can cause intestinal obstructions resulting in expensvie surgury at best and death at worst. We have a six month old Bernese Mountain Dog-he has Nylabones and rope bones and is never left unsupervised in the house-the only thing he has destroyed is an old kitchen rug.
