Great for our Lab!
Style: Classic + 2pk Ball, Size: 26in
Our Lab loves playing fetch and this is a great product to assist doing that. Great for open field, football-soccer fields, just any large open space. Another great use is scooping the ball up with ease.

Arm Saver
Style: Classic + 2pk Ball, Size: 26in
I loved this product as much as my dog! It saved my arm and the ball flew further than I could ever throw it myself. The rubber balls are very durable and are holding up very well for the ball chewer.

For medium sized dogs over 25 lb
Style: Classic + 2pk Ball, Size: 26in
The product is great, but for my little dog, it won't work. The balls that come with it are too large for her. I will give this out for free if the dog park for people who have medium sized dogs. Over 25 lb
