This dog toy is made from 100% all natural hemp rope. Dogs love them. The rope is 100% organic, strong and can be used as a chew toy or tug-a-war toy. We got the idea to make this from our dog Buddy (Border Collie) when he started chewing on our display rope in the shop one day. We told him "no, don't chew on that", then we thought, hmm. what about making him a chew toy from the rope. So we did and he has loved it ever since. Now he has his own hemp rope to chew on and not our display rope. This dog toy is made from all natural ingredients and does not contain any harmful chemicals.
