I got one for Luna and she loves it, she will sit there licking it and chewing the inside for hours.
I had horses in the past and the dogs loved the farrier because of this. I honestly don't understand the hype about antlers. I think they are way too hard, especially for the adult teeth. Puppies don't have that much power yet, but I never use antlers. For pups I prefer USA made bully sticks and large rolled-up pressed rawhide. (I know rawhide is frowned upon by many and a no-no in the fancy dog world) I don't use rawhide once their adult teeth have come in as they chew off too much in a short time. Never had a problem with this routine. Once teething is done, no more recreational bones (they get meaty bones for this purpose in their food).Inga loves to chew and eat horse hoof trimmings. Its a sustainable supply
