Stood up against Brody test
Set name: DinoBone 2-Pack XL
Brody is a 3yr old 85lbs pit mix and has always been able to completely destroy anything that says "able to withstand the most aggressive chewing " these products live up to the claim!! It has been at least 3 days since Brody has been chewing on the toys and they are holding their own against him! Highly recommended for aggressive chewers.

Indestructible??
Set name: DinoBone 2-Pack XL, Set name: DinoBone 2-Pack XL
I am giving this product 1 star but it really deserves 0 stars.
Their definition of indestructible is different than mine, my pit bull had the ends of this toy chewed off and splintered in 2 days, I'm praying that I don't have to take her to the vet because she might have swallowed some of the material that it's made with. I believe that this is a dangerous product for a dog.
I will be sending them back including the one that she chewed.

Durable
Set name: DinoBone 2-Pack XL, Set name: DinoBone 2-Pack XL
I don't really like buying these super hard plastic toys for my dog, but he's such an aggressive chewer that most toys are like throwing away our money. If he doesn't destroy it it's because he doesn't like it. But these last a while. He's had one of these for almost a month now. It has chew marks, and he chewed a couple of small pieces off, but it's mostly fine. He likes it when I spread peanut butter between the ribs. The only other downside (besides feeding my dog plastic) is that it hurts worse than Lego to step on it when you're barefoot.

My dog really loves this. She has been chewing on it since it first arrived and it still hasn’t been chewed up. This toy is truly indestructible.
