My old Brittney could tell by what clothes I was wearing... Hunter orange and he'd run over and jump in the bed of the truck. Camo and he would pout like a three year old cause he knew I was bowhunting. Come out in Biboveralls (My plumber uniform) and he barely lifted his head.

They say some breeds of dogs carry the IQ abilities of a 4-5 year old child. I know some very bright 5 year old kids and have had the pleasure of owning a couple of dogs that were impressive too.
