Recommend for very heavy chewers
Color: Grilled color
My aggressive chewers love these! It’s been a few weeks and still in one piece and man they chew them for hours on end.

Amazingly great product!
Color: Grilled color
I’m not just saying this, ok, this is not hyperbole: this is THE best nylon bone for chewing that I have ever purchased. And you get TWO of them for relatively less expensive than most chew toys give you one! I have 2 golden retrievers, and if you know goldens, you know that they are some of the most relentless and powerful chewers around. So I can’t give them almost any toy other than rubber stuff or it will be destroyed in a period of time that doesn’t make it worth it. One of them even figured out how to destroy a supposedly indestructible toy made out of kevlar! She was able to get into it through the seam, which is not kevlar ha ha. Anyway, I digress; I never even considered nylon chews because they suck! Usually. Usually my dogs in the past have lost interest with them in less than a day. I took a chance on these mainly because of the novel shapes, the fact that they give you two, and the low price. Both my goldens LOVE these! Not just for one day, but going on weeks now! I don’t know if it’s the flavor or what, but I will see them gnawing on one of them at some point every day. And they CAN’T destroy them (I knew nylon was good for that, but it was the “who cares” attitude of my previous dogs toward nylon that kept me away). Both the “ribs” and “steak” (quite clever) are a bit worn on the edges now, but they look like they will be around for years. You can’t go wrong with this product (unless for some reason your dog does not like the flavor, but the flavor seems to be what draws my dogs to them). I highly recommend this (these) as the most cost-effective chew toy I’ve ever purchased.

Great for larger dogs
Color: Grilled color
I think they were heavy duty and durable, but they were too heavy for my dog. The seller was excellent though!

It ok but a bit small for my golden and I have to supervise him.
Color: Grilled color
I don't recommend. Too big for my small dog. Too small for my big dog. They have similar bones but these just seem odd. ** WELL actually after some time they both will chew on them, especially my golden. Do be careful watch the dog while chewing. My home health care aid thought they were real. they are holding up well.
