Happy Dog of Cape Cod Premium All Natural Sliced Elk Antler Dog ChewsAll our antler chews are all natural as they come from free range Elk that are never given any steroids, unnecessary antibiotics or other growth promoting chemicals. Natural Elk Antler chews are much longer lasting than rawhide or synthetic chew toys, and even longer than raw bones. This is due to their high calcium content of these bone like natural growths. They are a great way to promote healthy chewing for dogs! These ELK Antlers are all FRESH!!
