I learned last year that racoons are tougher than they look.  We've got a big problem with them coming up on our front porch every night and terrorizing our cats and stealing the cat food.  One night I caught them on the front porch eating and opened the door to scare them away.  When I did my Australian Shepherds nearly knocked me down to get outside.  We've got two, and both of them are 50-55 lb. dogs that were raised in the country (no pampered house dogs here, they're tough) and it took both of them to dispatch one racoon.  I couldn't believe it.  There we are, all three of us, myself and both dogs, doing circles in the front yard fighting a racoon.  I should have thought about it before opening the front door because I should have known the dogs would go nuts if they saw the coon.  Lesson learned.
