My 11 month old super chewer lab got this as an early b-day present and had a marble-sized chunk out in less than 15 minutes. Very disappointing, since I read all the reviews of power chewers still going at it after months... My little lab puppy it seems has a stronger chew than a pitbull... whodda thought, right?

Took her an hour to destroy the Tux toy... As I type this, she's chewing on the Zogoflex ball... we'll see if that fares any better...
