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

A must have for dogs.
Style: Classic + 2pk Ball, Size: 26in
This has provided hours of entertainment for our dog. The Length was perfect and saves a lot wear on your back from not having to bend over as much.

Best dog throwing toy
Style: Classic + 2pk Ball, Size: 26in
Probably one of the best purchases I have made! The balls are far superior to any tennis ball. My dog likes to chew or bite down on the balls once she catches them and tennis balls ball apart. As to the actual thrower - the extra length on this one has helped me, I had back surgery and am not able to bend over I can reach the ball without too much difficulty. So to sum it up - best dog throwing toy I have purchase!
