It's funny how it's not the size of the dog that determines whether they're destructive machines either. Toys will last forever with my 90 lb male golden. But my 75 lb female will chew through Kongs, firehose material toys, ropes (she sure passes some interesting poop...lol) and such....she works her way around the edges until they're small enough for my male to swallow. Three stomach surgeries later, we give no cow hooves or bones and we keep a very sharp eye on how far along toys have been chewed, removing them when they're down to a certain size. Like a previous poster said, we do buy the cheapy squeaker toys just for a 5 minute treat...my male loves getting to the squeaker!!!
Our large black Kong has lasted for about two months this time. Maybe she's outgrowing the chew urge a little...
Gonna google the Big Mean Kitty thing....
