My husband wanted us to replace one from a different company that broke. It had to have a glow in the dark ball, since he sometimes plays fetch with the dogs at night. He couldn’t love this more. Says it’s so much better than the other one, the whole thing glows in the dark and it throws farther. According to him, it’s the best ever.

Glow In The Dark Ball

Size: 18in

I gave this 4/5 stars because the ball is a little small for my dog size so I was hoping the sizing was easier to read. It could have been an error on my end. The ball is great though! It lights up nicely when it is out in the sunlight or under a light for a long periods of time, it lights up at night so you can play with your dog at night when it is cooler!

Well designed, well built.

Size: 25in

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!

Size: Medium

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