This is the only toy my 45-lb rescue mystery mutt has NOT left in tiny pieces all over the place. He's an active chewer, and even the toys specifically for destructive chewers can't stand up to more than 20 minutes or so. Moreover, it flies so well in the park, is easy to see, and the springy shape makes tug fun for both of us. The shape allows him to wiggle and toss it to himself - so cute, and he keeps himself occupied safely with my supervision. We are officially West Paw devotees - TOTAL WIN.
