Defective cracked
Size: Large (Pack of 3), Color: Orange, Green & Yellow, Pattern Name: Dog
The stuff inside was cracked. It took my dog a few minutes to get it out.
I bought these from other stores in person and didn't have any problem. It must be from shipping and handling.

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.
