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.
