The Buck Bone Organics Deer Antler Dog Bones are a high-quality, natural treat that is perfect for dogs of all ages. These antlers are handcrafted in Montana and are specially selected for a combination of weight, density, and color. Each year, wild deer shed their antlers naturally, providing a perfect eco-friendly, super-food dog chew. We then hand sort, inspect, cut, and sand each individual piece to be placed in our resealable pouches. The Buck Bone Organics Deer Antler Dog Bones are a great way to support clean teeth and an excellent source of protein, calcium, and phosphorus.
