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. EASY CHEWS Easy Antler Chews are specially designed for very young puppies, older dogs or 'lazy' chewers Hand cut lengthways to expose the tasty nutritious inner antler marrow, making it easy for these dogs to enjoy the tasty bits without too much hard work! Still clean and safe with low odour, to human's anyway! These chews are best for dogs that do not have strong jaws and are not strong chewers.
