Dude, you are on my level...RIGHT ON! Well said! The Only dogs I've ever been bitten by were 2X Blue heelers, 1X red heeler, 1X Rottweiler and 1X Border collie. My Jacks will not bite another human unless you physically abuse the hell out of them... I was walking in public minding my own business on all occasions when I was bitten by large dogs. Still have the scars. Anddddd... a pedigree Jack would belt the living p*ss out of any Aussie "pit-bull" any day.
