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.

This Ball Was Awesome........ ! (NOT FOR CHEWERS)!
My young Labs are not heavy chewers but they LOVE their ball time! They loved this ball and it was soon the new favorite. It was bouncy, solid and good fun to throw and fetch. It was the same size as a standard tennis ball, perfect! There is a little light inside which is charged by USB C and makes great ball play time in the dark. However, I just went to charge it and I noticed that the little rubber bit you turn to get the rechargeable light out had been bitten and chewed all around it so I can no longer get the light out. The ball is made of really hard silicone just not around the edges of this part, its plastic and I did not notice. Now I have two very sad puppies who want their ball back. It worked really well for so long and it has only just broken. I do not think they have chewed it that hard either, just from the retrieving it and bringing it back to me. They really loved this ball, the way it glowed it the dark, how high it bounced and the weight of it. Good value for money if your dog has a soft mouth!

Wonderful for dry feet
Material Type: Black - 3 Pairs, Size: X-Large
I have been dealing with dry skin and problems with the heel of my foot, so I thought I would give these a try. I am so glad I did. They moisturize beautifully. A must is you are having trouble with your feet.
