My dog Lobo is a 130 pound German Shepherd who just loves frisbees. Regular frisbees would be trashed as he walked back to me after retrieving them the first time. I had better luck with disc golf discs, but he would still manage to ruin these after a week or so. He was never left with the toy. This always happened during retrieval. He aslo played with thos mini tires. They lasted longer but were hard to throw far. Plus, eventually, he did rip them appart. I bought this present disc and thought for sure I would be making use of the guarantee. He has been playing with it for many months now in all kinds of weather. After seeing how durable it is, I no longer take it away from him immediately after play and let him keep it in the back of my truck while driving to and from our play sessions. And I never dreamed that it would fly as good as it does. It flies very well and far. We are very happy with it. And happy with the salesperson who recommended it to us.
