My dog is a heavy chewer and loves antlers. However was getting rather expensive as was buying xl from another online pet supplier for £16 plus. They were only lasting a week if lucky and also the last couple were small nobbly bits and useless for dogs to chew. So decided to see if I could find a different supplier and buy in bulk and get cheaper. That when I found Ace Antlers and must admit was not sure what I would get. I Ordered 1kg xl and received 6 good size chunky antlers. After week one my dog is just starting to chew it down and really seems to like them. I will definitely be buying more and have recommended already to friends.
