I just wanted to say how thrilled I am with the Dog Bone Shed Antler Retrieving System! I was training my dog Ranger to be a search and rescue dog, but due to life demands I was unable to continue. I wanted something that would satisfy his search/hunt, scent detection, and retrieving desires! The Dog Bone Shed Antler Retrieving System has met all of those needs! Plus my 10 year old son loves to go out and do shed antler training with me and Ranger! Your product has made one dog, one boy, and one mom extremely happy!
