I had bought the puppy pack nylabones so you get one each for 2mo+,3mo+, and 4mo+. Well I gave Gunner the 2mo+ "puppy" two weeks ago and he's already chewed off one end of it. A few days a go I gave him the 3mo+ "edible" bone and he finished it within 36 hours! I have the 4mo+ "durable" left but he's right at 3mo so I was wondering if I can give it to him? Is it based on how much they chew or how developed their teeth are? The "durables" sold singly do not have an age on them so I wasn't sure how strict it is. I was really thinking of getting him one of the Galileo bones but would that be too big and hard? I've read the Orbee bones are good, can puppies have those? And how long should a nylabone last (the nylon or edible ones)?
