100% Natural Recreational Chew for Dogs. The deer antler is a very hard bone that does not splinter, so it can last your dog weeks or months. It has a high content of calcium, phosphorus, and minerals. Chewing it will keep our dog's teeth healthy, strong, and clean. Additionally, it is a great ally to combat stress and boredom, and its marrow content makes it irresistible! This deer antler, being split, will allow easier access to the marrow, the most attractive part. All deer antlers are collected from the forest, originating from the natural shedding process that occurs once a year. Available in various sizes to suit the needs of each dog.
