My little one goes to town on these.. I have bought several.. I get scare when he chews all of the end down and then looks like little pieces of the fiber are coming off. so I throw away and buy a new one.. at least they are cheap enough to do that for cost. He loves them and nothing else gets chewed.

I will buy this again if it ever wears out! 🦴

Flavor Name: Bacon, Size: Medium

My dog loves it, he’s a Boston Terrier. Perfect size for a Boston. It is well made, doesn’t fall apart and there is no stink! Safe to let dog use by himself and good value for the money.

Only bone for my dog

Flavor Name: Chicken, Size: Medium

These are the only bones my dog will chew on. He loves both the chicken and bacon flavored. I just have to watch him as if they get too small I don't let him chew and will give him a new one.

Size information reversed. Smalls are medium and mediums are small.

Flavor Name: Bacon, Size: Medium

I love the product but the description is frustrating. I ordered the medium size bones expecting the 7 inch bones, but recieved the 5 inch bones. Apparently if you want the 7 inch bones you should choose small instead of medium. That makes no sense and is so irritating.
