I was told by Gunners trainer to get him raw beef knuckle bones to keep him safe and protect him from splintering bones and rawhide bones that are terrible for dogs. These bones can be purchased from a slaughter house and are way cheaper than the junk at pet stores that are bad for them. they don’t splinter and have bone marrow that they love.. i got them for him today and he loves them i encourage you to give these a try and help that pup with their chewing urge and keep them safe and healthy. hope this helps someone.. it is proving to be a perfect solution for Gunner
