Chuckit! Air Fetch Ball, medium, two per pack. The hollow lattice shell lets air pass straight through, so a dog can breathe freely with the ball in their mouth — the reason this one suits flat-faced breeds and dogs that fetch until they're winded. It floats for pool and canal play, weighs next to nothing, and the open sides double as a treat pocket for training. Works with every Chuckit! launcher. 2.5 inches across, sized for dogs roughly 20–60 lbs. The ball should be easy to carry but too big to fit all the way into the mouth.
