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.

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!

Not really what I paid for.
Flavor Name: Bacon, Size: Medium
I have two major chewer dogs, and one of REALLY chews on everything. It’s super difficult not spending an average of $50 every 2-4 months on chew toys because they go through them so fast. When I got my first boy I saw his chewing habits so I looked for a durable chew toy brand. Nylabone was everyone’s favorite so I tried two or three chew toys for him after attempting other brands. He’s six years old and this past Christmas I JUST threw away his very first chew bone. It lasted over 5 years. I was ecstatic after year one! A heavy duty chew toy brand that actually did was promised! Naturally I stuck with Nylabone, never having an issue with any of their toys until this one. Cheeseburger bacon flavored/scented was my go to for this second puppy I just got with the same, if not more, super chewing habits. He loves trying to steal our bacon and burgers so I’m like, “Okay. I’ll try this one.” It arrives, I open it. It smells like freshly burnt rubber from tires and neither of my boys will touch it. I’m also wondering how this can be durable if I can literally bend without trying much. I’m overly concerned with them digesting it and will probably toss it in the trash since my youngest boy has stomach issues already and doesn’t need this thing irritating it. In short, if you think yours will smell like bacon burger go for it. Just make sure your dog isn’t a super canine chewer because I doubt this thing would last an hour with even one of my dogs and that’s if they would actually touch it.

Ok
Flavor Name: Bacon, Size: Medium
Not for powerful chewers. Did not hold up to Corso pup or Belgian Malinois.
