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.
