Sure, fetch time is a blast. Sometimes so much that you and your pet are having too much fun to pack it in when the sun goes down. But rather than lose tennis balls in the twilight, you can keep the fun going with the Chew King Glow Fetch Ball Combo. With just a few minutes of bright light exposure -- from the sun, a lamp, even from the flashlight built into your smartphone -- these fetch balls glow in the dark so your furry sidekick can find them after every toss. It makes cleanup easier on you, too, if your pooch is just too tuckered out to retrieve the last throw of the day! The dog toy set includes two styles and three sizes so you can mix up playtime and keep fetch interesting. The large and medium lattice balls have a fun, easy-to-grip texture, and help the ball bounce erratically once it hits the ground. The two medium fetch balls make a great replacement for tennis balls, and can even hold a treat. Tuck a biscuit inside, flip off the switch, and watch an enthusiastic light show on the part of your pup! Get a set and let the fun go on, even after the sun says the day is done.
