Great for a medium chewer!
Flavor Name: Bacon, Size: Medium
Bought this for my Standard Poodle. He's a year old, 65 pounds, and loves to chew but doesn't have the jaw strength of some of my previous dogs (I think my pit bull would have destroyed this in short order!). This works well for him; it's his favorite toy for fetching. It bounces in an unpredictable manner when you throw it so he has fun chasing and retrieving it. It is heavy so be careful throwing it in the house! I like these shapes better than balls that will roll far under things and be difficult to retrieve. I don't know that I would leave him alone with it in case he did chew a piece off, but for monitored play I highly recommend. I'll definitely buy more if these ever wear out but I don't see that happening in the near future!

Smells like rubber.
Flavor Name: Bacon, Size: Medium
I bought this flavored nylabone for my dog because he had one that he just loved and it finally had to be thrown out. So I bought him this one and he won't even chew on it. All it smells like is rubber. No flavor smell AT ALL. But our other dog chews anything and he chews this so I kept it. I won't buy nylabone again.

Super chewer approved
Flavor Name: Peanut Butter, Size: Large
One of the few safe chewy bones for a super chewer. Very durable, an appropriate price, and a good size for our 70lb pitty.

Very durable
Flavor Name: Bacon, Size: Medium
One of my dog’s favorite toys! He destroys everything and is such a powerful chewer but this one lasted longer than any of his others and he really likes it!!! I bought another for back up so he doesn’t have to go without!

Great chewy!
Flavor Name: Bacon, Size: X-Large
Super durable chew toy! Our 9 month old golden retriever absolutely loves this thing. Even our 13 lbs malshi runs around with it! Great price for how well it’s holding up.
