The Antos Antler is 100% Natural chews for dogs. Our Antos Antlers are from red deer, much of which is from Scottish highland herds, and have simply been cleaned (with no chemicals) and cut to various sizes/weights for dogs to chew on. Sharp points have been removed to make them safe. Antos Antler is a healthy chew, full of minerals and calcium. They are long lasting, and as they are unprocessed, they will not splinter either. The Antos Antler satisfies a dog's natural urge to chew, whilst also helping to strengthen and clean teeth. They are also low in Fat. There is very little odour from Antos Antlers, and as your dog grinds down the antler over time, there is also very little mess. Being a naturally grown chew, no two antlers are the same. Some are a harder dark brown colour whilst others are a softer greyish/white. They also come in various shapes and sizes, keeping your dog interested for longer. Antos deer antler chews come from a sustainable, natural resource. Feed Material. Not for human consumption. Safety: To avoid a choking risk, take the Antos Antler away from your dog once it gets worn down to a size which your dog could easily swallow. Always supervise your dog when feeding. Antler is a natural product and can splinter in some cases.
