It easily mounts to just about any tree by wrapping it around the trunk, hanging it from a branch, or a combination of the two. Also, reviewers note that it’s easy to swap out the included rope toy with a new one if need be.
Promising review: “My pitfall puppy has destroyed every ‘tough’ and ‘durable’ toy possible, but this little guy? Lasted us almost a full year. Our older pitbull/lab is incredibly strong, and it still hasn’t broken under his weight. It tired them out, too, which is great. I also found it’s great for training the dog to drop/leave it because they can’t run away from the ball, which makes it easier to train.” —Ashlyn
