The stick facilitates powerful, long distance throws. The ball makes a light whistling noise (to help your dog track the ball) through the air, flys far, and has held up well. I live in an area with mountain lions, and they often hunt at night, so I haven’t taken advantage of the glow-in-the-dark feature.

Yes!

Durable. Squeak doesn't last forever with my aggressive chewers but crinkle does. Best balls.

Balls

Size: Medium

My dog loves chasing these balls. He seems to love the squeak! They fit the chuck it stick perfectly, and are great replacements for the originals that came with the stick.

Nice set of balls

Size: Medium

The squeaker quickly became my dog’s favorite ball and has replaced the fuzzy tennis balls. My dog is a nonstop fetcher and these chuck it balls are durable and fun.
