At least 6 years ago, I purchased our first Huck large ball. We had 3 adult springers, 2 of which were extremely aggressive chewers. Since then we've added 2 forever fosters, followed by 2 puppies. It wasn't until the second round of puppy teeth that the original ball showed signs of distress. We put it up until her puppy teeth shed and the ball is still in great shape. Since then, I've purchased a Tux toy and 2 more large balls. Our guys chew a lot, when they aren't chewing they're carrying these toys around. Thanks for a great product, made in the U.S.A.
