Truly indestructible!
My 80lb English bulldog, that literally can chew his way through a tree trunk if left to his own devices, has not been able to destroy this toy. Rather, he’s enjoyed chomping on it bc of the scent and heavy weight for more than a year. Good value and will hopefully last many more years.

Nice toy
Flavor Name: Peanut Butter, Size: Large
I bought this toy in L size for my Frenchie cuz he is a hard chewer, and it ended up being too big for him. He seemed to love it though. I’ll reorder a smaller size

The warnings on the box say it's dangerous, the product page said it was safe.
Besides being much smaller than expected, this is from the box:
+ It's important to select the proper size & type of chew for your dog's age, weight & chewing strength. - "The Amazon page says it's 'Safe for All Dog Sizes.'"
+ Always supervise the use of all chews & toys - "The Amazon page says 'a safe alternative to edible chews when you can’t be home.'"
+ Product is not intended to be eaten or ingested. If you think your dog swallowed a piece, take the product
away and contact your veterinarian. - "The Amazon page says it 'provides a safer alternative to real sticks. Safe non-toxic. A safe alternative to edible chews when you can’t be home."
I've been disappointed by Amazon purchases before, but this is the first negative review I've written because this thing seems dangerous for dogs. I would report it to Amazon, but I can't figure out how.

It's not for aggressive chewers.
Flavor Name: Peanut Butter, Size: Large
The bone looks solid except for the brown strip wrapped around it. My dog chewed a piece of it off and tried to swallow them. I had to pull two strips of hard plastic out of his mouth. I threw the bone away.
