There’s a film with James Belushi, “K-9, Dog’s Work”.
And I only found out today that K9 (kay-nine) in English sounds like “Canine”, which is literally the scientific term for “Dog” (hence, for example, the dog food “Royal Canin”, etc.)
That’s why K9 is the standard name for K-9 units in US police departments.
P.S. And “canine teeth” in English means “fangs”.
So literally, Dracula, Nosferatu, and other Blades ran around with “canine teeth”.
