Our Dog Is OBSESSED – Night Play Game Changer!
This light-up dog ball is a total hit in our house. As you can see from the photos, the glow is bright and easy to spot even in complete darkness, which makes nighttime play so much safer and more fun. The motion-activated light turns on instantly when my dog nudges or bites it, and the 90-second auto glow is perfect.
The silicone material feels soft but durable, gentle on teeth, and my dog loves carrying it around. USB-C charging is super convenient, and one charge easily lasts multiple evening play sessions. It’s also water-resistant, so no worries about grass or dew.
Perfect size for small to medium dogs, and it keeps my pup engaged and active after sunset. Highly recommend for anyone who wants fun, visible, and stress-free night play with their dog!

Better yet imporbable than the original LaRoo Ball
I owned the LaRoo v1 (old version of this ball) my 100lb lab loved it. It was the first light up toy to resist the strength of this jaw. It glowed bright enough and stayed on long enough to be fun for the dog in the darkest settings. Unfortunately I was stress testing it and he was able to unscrew it at some point and destroy the ball. Supervised it was great.
Onto this new one. It glows brighter for longer, great improvement on the original red one. My issue comes with the cap. They changed it from a threaded screw on cap to a bayonet mount (push in turn 1/16 of a turn its locked) the issue is that the bayonet plug was a few mm too short in tolerance and slipped out on our first play session. Its not nearly as secure as it once was. That being said a couple rounds of electrical tape around the perimeter of the plug and it now fits securely in the slot and is safe for puppy. This is a hard ball comparable to a baseball in size and softness. It doesn't make noise. The dog LOVES it. Its his favorite toy. If your dog plays fetch they will love this toy.

Not practical
I really wanted to like this ball, but it didn’t work well for us. The rubber is very hard and heavy, which made it difficult for my dog to catch it in the air and it was less enjoyable to play with overall. After only a short time, the plastic lid got stuck, and now I’m unable to open it to recharge the ball.
The light feature is a nice idea, but between the hardness of the ball and the charging issue, it just wasn’t practical. Disappointing quality for the price.

Perfect night-play companion
This ball is a total lifesaver for our evening routine. It’s perfectly suited for nighttime, the glow is so bright and consistent. My pup used to get so disappointed when the sun went down because it meant we had to stop playing ball. Now, the fun doesn't have to end! He never has to feel let down by the dark again. Seeing his face light up (literally!) is the best part.
