We have a kong for Oz. They can't chew it up, its' too hard. We have the smallest size for our pup, who weighs about 5 lbs. I would not FILL it with peanut butter either, but if you want to smear a small amount of all natural peanut butter inside it that would probably be ok once in a while. For Oz, I use it as his irrestistible treat for going into his playpen before I go to work. I fill it with a good quality wet dog food and stuff one small hard treat into that. Takes him a while to work through it and it is his breakfast. When I let him out of his playpen after work he has a great time tossing it around trying to get every last bit of food out of it.
