When your dog's outfield includes a water landing, you want to make sure your ball of choice not only floats but is visible for the catching and fetching. After all, the sport isn't fun when the game has to stop because the toy can't be located. The glow-in-the-dark (and in the daytime) Meteorlight ($10) uses an LED light to shine brightly in all surroundings.The standard size is perfect for use with a Chuckit! launcher if the dog's going long or bounces if he prefers the dribble. Don't worry, there's an off switch for when play is over. Good game!
