I have a year and a half old Australian Cattle Dog at home that destroys every toy we've ever brought into our home in a matter of minutes. All of the name brand products like Kong and Nylabone that are supposed to be "virtually indestructible" are in pieces soon after we give them. I bought this dumbbell for Boone last Christmas, and it is the ONLY toy that has ever lasted. If you have a heavy chewer or a dog that loves to play tug-of-war or fetch, I HIGHLY recommend this toy. GREAT product!!
