Our 8mo puppy (40lbs) chewed up a bunch of plastic frisbees before we could ever use them as frisbees, so I wasn't sure how this would work out. GREAT NEWS: she absolutely LOVES it! It's her favorite toy (and she's had too many). I haven't EVER thrown it without her speeding after it and bringing it back. I don't let her chew it up because it's too good for fetch.
So far, no holes/rips even after she's sort-of-shared it with her puppy BFF. Soft enough that we may have played fetch indoors when needed. Can't recommend the larger option enough, the orange is great as it's visible in grass. Excellent Ruffwear, as expected!
