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.

Keep my dog entertained…for a while!!
My dog absolutely loves this toy! I spread a bit of peanut butter on it and he gets so excited every time. It keeps him busy for a few minutes, though he licks it clean super fast. Still a great way to give him a little treat and mental stimulation.

Performs as promised. Great value.
FANTASTIC!!! More than expected. We use it outside. Our 10 m.o. GSD loves it! It dosen't bounce like a ball. But it gives her plenty of exercise. The chewability is unbelievable. Definitely great product. Will buy & recommend for any chewer pup!
