Great for dogs that chews a lot up everything
Size: Medium (Pack of 1)
Great for a puppy (large puppy) that chews a lot! So far, this toy is indestructible - and is the first toy she hasn’t chewed into bite size pieces! She loves to play with it all the time.

Great for my Sheprador
Size: Large (Pack of 1)
Dog loves it and it's indestructible. Dog loves chewing on it. The little spot to add treats gives the toy a great life as a distraction while I'm gone. It bounces pretty well too. It's cute but I wish this size had different colors. Black gets lost in my house easily.

Tough!
Size: Large (Pack of 1)
Our dog is a chewer! Fabric toys don’t last - he enjoys ripped them apart. This lasts quite a while. I do watch it because after sometime (month or so), he does get it start separating. He actually got it in half once (looked “interesting” on my floor when we found it and made for a good laugh). We will continue to buy them.
