Wow! Those are some massive dogs.
Yep - little sister Katie (brindle) weighed in at a dainty 199# last October at her annual check-up while big bro Charley was an even 202#. Their bark is their only weapon - other than image (which is everything for some).
They even guard the trailer when camping in the summer - their defense strategy is, if strangers aren't intimidated by size and bark, drown'em in drool.
