aside from scooby do and the rest of the classic popular bigname dogs out there, a factor of fun in classic cartoons was a certain so-called man's best friend. right! the dog of the house! you knew if there was a dog somewhere lurking around, it meant trouble! what made it worst for the character, but funny for us, was that most likely the dog will bite. you knew the bite would come up when he made a little bark before he bit him/her. mailmen had the hardest time. one of my favorite watchdogs was grizwalt from Top Cat.
