This ball is a little on the heavier side. Which makes it bounce and "roll" farther than expected. I bought this ball over a year ago from a retail store. All the dogs at the local park loved it, so, like half the toys I buy, I left it there for all to enjoy. It lasted for over a year in that park. Through sun, rain, sleet, snow, and mud. Enduring temps from +100°F to -40°F, commercial lawn mower blades, and an endless cavalcade of dogs both big and small and their humans, incurring only a minor nom to one corner. Said nom in no way affected the integrity, safety, or useability of the ball. In fact, as can be the way with scars, it only added to its fascinating and quirky nature. Sadly, this marvelously indestructible, endlessly entertaining ball disappeared. Perhaps subject to an over-zealous throw by an unsuspecting human, unaware of the magical momentum this ball can maintain and subsequently eaten by the ever encroaching blackberry bramble that borders one side of the park. Perhaps taken home by a pup bereft of such a wondrous toy of their own. Perhaps it met its match, and was demolished by a truly ferocious chewer and it's broken, scarred remains deposited, without ceremony, into the trash. In any event, I promptly bought a new one. I recommend you do the same. Especially if you have a dog who loves to run after balls but are like me, and have a pitiful, practically non existent, throwing arm.
