No more slobber
Color: Blue Dog Ball Launcher, Size: One-Size
Works as described. Can throw a tennis ball a mile. Keeps the slobber off my hands.

Squeaker Pinches Hand
Color: Blue Dog Ball Launcher with Squeaking Handle, Size: One-Size
I toss balls 50-75 feet into the air. Works our my dog. I can actually throw a ball over 150 feet, so the dog gets a good workout. The squeaker is unnecessary and it does pinch my hand on a long toss.

Just as good as an actual Chuck-It
Color: Blue Dog Ball Launcher with Squeaking Handle, Size: One-Size
This is much cheaper than a Chuck It. And it’s just as good. My dog loves it.

Game changer
Color: Blue Dog Ball Launcher, Size: One-Size
This has been such a game changer in playing fetch with my dogs. The ball fits inside great and it throws smoothly and goes quite a distance.

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.
