These raw marrow bones come from the same free-range, grass-fed, hormone & antibiotic-free cattle as used in all of Steve’s Real Food other beef products. Give to your dog for recreational chewing, mental stimulation and teeth cleaning (not as a meal). The 4″ size is great for dogs 30# or over, and come two to a bag. The 2″ size is better for smaller dogs, and come three to a bag. Please always monitor your dogs when they are chewing bones.
