This tire is great.... if you have a small to medium dog. It's still very good for a large dog it's just harder to grab it when they have it in their mouth. It's great to throw in the yard, it rolls really well. My Am. Staffy/Bully loves it! For the price you can not go wrong! I'm sure this one (toy) will last quite a while!
