Cajun, my Labs love those bones too and I get them doubly tired by only giving one of the three of them a rawhide at first and letting them go to it in my big backyard. The other two will chase the the one with the bone until they're all tired and then I'll give the other two their bones. With three young dogs, its hard to keep them tired enough to not be stircrazy especially when its this cold. I find that if I don't give them stuff to chew on, they'll chew on what they find, including garden hoses and my hardwood ax handle among other things.
