AMAZING!
Color: Pink Blue
I have never written a review before, and I shop 4-5 days a week on Amazon. My 5 month old puppy LOVES these chew toys. When I first opened the box I was worried because they were so hard, but Poppy went crazy. He chews on them, tosses them and retrieves them, runs in circles around them and barks, and when he finally settles down will chew them and make these pig snort sounds of contentment. I have bought a lot of toys for my new puppy… But these are the best by far!

Toy broke in two
Color: Blue
This is a great toy for aggressive chewers. My reason for 3 stars is my dog dropped it on the tile floor the second day she had it and it broke in two. Not real happy with that. Update: The seller has been proactive and accepting of the very minor issue of the toy breaking. Responded within 24 hours and issued a refund. Because of their response I am changing my review to 4 stars.
