Great long lasting chew
Flavor Name: Peanut Butter, Size: Large, Flavor Name: Peanut Butter, Size: Large
We really like having these bones on hand to keep our power chewing pitties busy. The large sizes are super convenient and long lasting, and our dogs really seem to enjoy them. We have gone through several orders over the last few years, and I anticipate to keep buying this brand.

Great for heavy duty chewers
Flavor Name: Steak, Size: Medium
Our two dogs love these bones. They’re very durable for heavy duty chewers and it takes them a fairly good time to get through them. They must love the taste because it’s the bone they first pick up. I’ve gotten two flavors so far, beef and the peanut butter. Our dogs love them and because of that so do we.

Seems great, but not for my lab
Flavor Name: Bacon, Size: Medium, Flavor Name: Bacon, Size: Medium
I am rating this, to some degree, from a hypothetical standpoint. It SEEMS like a great bone. It SEEMS like it will last quite a while and withstand some avid chewers. However, I can't say for certain because it just wasn't well-loved by my Black Lab. She has a penchant for chewing animal bones. She loves to find wildlife bones in our yard and munch on them, so we do our best to provide healthy chewing options in the house. She will go to town on a cow's joint and even enjoys a peanut butter filled Kong from time to time, but this bone just didn't meet her expectations. It's not a bad bone. It has a very rugged feel and seems like it would be safe if bits and pieces were to begin coming off, like they're safely edible. I guess (and I can't say for sure..) it just doesn't have as much of a meaty flavor as many dog's like. If your pup is a Nylabone chewer- or likes to chow down on your loafers- this bone may be a perfect new addition to his/her toy bin.

Bone for destroyers
Flavor Name: Bacon, Size: Small
4 months ago I Bought this bone for my 90lb lab who destroys all his bones, but not this one! It barely has any teeth/chew marks on it and it’s one of his favorites. It was a great find and I’ll be sure to buy again. If you have a dog that destroys bones I’d give this one a try.
