This toy is meant to be a fetch toy and not a chew toy. It will hold up with light chewing (like between throws) but don't expect it to withstand hours with a heavy or even moderate chewer. Material and Durability: This toy is made out of a softer rubber than other dog frisbees we've used, to give you an idea it will easily bend in half (around the ball of course) with little effort on your part, unlike other more stiff frisbees. The rubber is thick enough that, as I said above, it will hold up to light chewing and because it is so malleable it is less likely to break off (but more likely to crack) and seems like less of a chew magnet for my dog. The ball if made of the same softer rubber and I wish it were made out of a harder rubber like the Cuz balls. This is not nearly as durable as those Cuz balls and within a few days of playing with this the ball stopped squeaking because she had broken through the rubber (not enough to see holes but pretty much cracked it). So the same material that, in my opinion, makes the frisbee part more durable also makes the ball less so. My dog LOVED this thing with the squeaker in it and now that the squeaker is no more she still likes it but she's not as enthusiastic as she was before. To be fair, she DID seem to realize the middle was a ball so she put in some effort to try to detach it to play without the frisbee part. :) She was unsuccessful of course but even with her attempts and her squeaking the ball in between throws I would think that the ball should be able to withstand her playing. After all, the squeaker ball was made with the intention of the dog chewing it to make it squeak, right? While this seems perfect for a game of tug for dogs, I wouldn't recommend it. I think a harder rubber frisbee would be able to better sustain the tugging than this. As I said, while I think this is less likely to break of in chunks, it is more likely to crack and thus tear. Play: Like another reviewer wrote (thank you btw, it was a very helpful tip), I throw this vertically so that when it lands it will roll for a little bit. This does not go as far as a ball even with the roll at the end. Without it, this wouldn't be a very good fetch toy at all. That being said, don't expect to get too much extended play even with the roll...it takes my dog less than a second to catch up with it rolling. I guess I don't know why I expected otherwise, I mean really, how fast can a rubber frisbee roll? :) Also, if it happens to veer off course and roll to one side it doesn't really make my dog chase after it (like another reviewer mentioned his/her dog doing). Instead, she'll just trot after it and pick it up...it's too slow to really engage her in any kind of chase. As far as the squeaker, take into consideration if you intend to play in the yard with neighbors around. If you've never heard a squeaker ball before, they are much louder than the squeakers in stuffed dog toys. If your dog loves squeakers as much as mine does, each throw will be followed with laps around the yard squeaking the frisbee. So...in a way it's almost a good thing the squeaker ball died after a few days because it is loud and I did feel a little bad for my neighbors. Misc: This is easy to clean, of course, being rubber. My dog's favorite fetch toy in the whole world is a rope ball with a rope attached...that turns into a mud ball easily and is much harder to wash. I definitely appreciate ease of cleaning in an outdoor toy. Overall, I was between a 3 and a 4 on this and went with the 4. My dog likes this toy but without the squeaker this is not her favorite. For reference my dog is a doberman.
