These sustainable antler chews are 100% Smurfie approved! He hunted them out in the unit before I could even put them away and he now has one at Plastic Freedom HQ and at home! The reason I LOVE these is because they are from Grade A and AA, Red Deer antler which are naturally shed, responsibly sourced, traceable and sustainable, many from the highlands of Scotland. SUSTAINABLE CHEWS These chews contain a number of good minerals and they are incredibly hard and long lasting. Your dog will find them exciting and irresistible. This is a totally natural product, free from additives or preservatives, its hypoallergenic, just pure and natural! PUPPY SIZE These puppy chews use the antler tip, which are the most nutritious part of the Antler. These are great for puppies or miniature breeds, full of flavour and small in size. Great for teething puppies to gnaw on.
