Plastic cut my dog
Color: Mixed, Size: Medium
If your pet chews a lot do not buy. My dog chewed the plastic and cut her nose when grabbing the toy because of how sharp it became.

Great for aggressive chewers
Color: Mixed, Size: Medium
This toy held up well. My dog is a very aggressive chewer and will shred apart any toy she can. She was not able to tear up this one. I have not found many toys that she doesn't destroy

Good buy
Size: 6 in, Color: Blue
A winner with our GSD. He’s not a super aggressive chewer but it has still held up and is a favorite.

Terrific toy for heavy chewers
Size: 6 in, Color: Blue
My dog loves this! Chews and plays with it constantly. These will last a long time, however, eventually they begin to break down. THEN GET ANOTHER, lasted a couple months with constant chewing.
