The perfect toy for dogs!
Style: The Duo
This is perfect when you have 2 dogs who love to play Fetch! They no longer have to chase after the same ball! The balls that come with it are very sturdy, and the launcher sends both balls far enough away so that both dogs get plenty of exercise. It’s definitely worth the price!

PERFECT RETRIEVING TOY
Style: EcoFetch
You can barely whip it and it sails far and fast. This is the perfect retrieving toy for my GSP. She's used to average and we now have a small yard, so the dog park is where she gets to run hard and fast. You can also throw tennis balls with it, which is a plus for when her sister steals her ball.
5 star fun!

Perfect for puppy play

This is perfect. Works great for a smaller yard and the ball holds up to puppy teeth!

Easy to use for this old folk!
Style: EcoFetch
If you have a hard time to bend down and throw, this is perfect! It allows you to pick up the ball with little bending over. It also gives much further distance to your throws. Great quality to both the ball and wand.
