Night play
Size: One-Size-for-Most
My dog like many other dogs loves to play. We needed a ball that fit into the handheld thrower we had but something that we could find it at night. This has been wonderful!

It stopped working after three play sessions
Size: One-Size-for-Most
I thought this ball was great until a week later it stopped blinking and got lost in the snow. We only played with it for three days for 20 minutes at a time. It should’ve lasted a lot longer.

It’s absolutely perfect for fetch in the dark!
Size: One-Size-for-Most
We needed to find a glow in the dark ball to run our over active dog after dark ( gets dark now about 5 pm ish) I was hesitant to buy this ball at first. We went to try it out and it totally blew my expectations! The ball really glows, it’s a durable rubber and when it hits the ground it lights up blue and red. Incredibly satisfied and just ordered 2 more. If you need to run your dog in the dark, this is absolutely for you. Highly recommend it

Dog loved it
Size: One-Size-for-Most
Great! My dog loves taking it outside at night so he can see where it goes easier. Super bouncy, he has had it for over a year now and still not destroyed. Perfect size for his mouth too and easy to clean.
