Chuckit! Ultra Ball, large. The one most dogs pick out of the toy box: an extra-thick rubber core built for high bounce and hard use, with a textured surface that's still easy on the mouth. It floats, so it works at the pool, the canal or the beach, and the bright orange shows up in long grass. Fits every Chuckit! launcher in the matching size. 3 inches across, suited to dogs around 60 to 100 lbs.
