My puppy's not quite 5 months old, and doesn't eat his toys, but certainly loves to chew, and if I don't have something at the ready, then the furniture and baseboard molding might suffer. Since I got him at around 12 weeks, I've given him good quality bully sticks. He loves them and they last forever, well, until one of the older dogs gets them. And Merrick, which makes the bully sticks, also makes the Miss Porky chews, and these are not as messy as smoked, crispy pig's ears. And, finally, I go to local farmers markets and look for the largest knuckle bones I can find. He works on one of those when I want a quiet shower and time to get dressed without having to worry about what kind of mischief he's getting into.
