Learning curve - but super fun
Color: Blue Dog Ball Launcher with Squeaking Handle, Size: One-Size
Okay- don’t get me wrong I know how to use a chuck it. But the handle of this has a squeaker - which is fantastic to get my ADHD dog to focus! Buuttt beware- it will take off your fingernail if you aren’t holding it properly when throwing. I learned that the hard way. Twice.

BUY IT!!
Color: Blue Dog Ball Launcher, Size: One-Size
Great product!! Releases the ball nicely and saves my arm from dying at the end of the day. The construction of it feels flimsy but for someone who uses it AT LEAST 3 hours EVERYDAY, I would say it's pretty good quality. Would highly recommend!!

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!
