There was a TV series based on the 1972 Movie "The Night Stalker" that started around 1973 or 74. It starred Darren McGavin who played a reporter investigating a serial killer who later we realize is a Vampire. Sounds tired doesn't it?????? it's not.......there is a scene in the first episode where Kolchak spots the suspect in a parking lot, and you don't really think it's a vampire until two Dobermans charge the figure and then the next thing you hear is two "Yikes" as he kills the dogs in mid-air. It scared the bejesus out of me, and I don't scare easily.
I don't know if it still holds up to scrutiny, but it was satisfying every week when you see Kolchak tackle another strange mystery that always involves a dreadful supernatural figure or a 'haint' as some folks call them. I'm pretty sure it was in B&W, but back then I only had a B&W TV......who knows.
