Watchers II (1990)

Watchers II (1990), as the title might indicate, is the sequel to the Corey Haim-starring flick Watchers (1988) based on the Dean Koontz novel of the same name! This time around, the shape-shifting golden retriever from the first film is taken in by ex-Marine and fugitive Paul—played by The Beastmaster himself, Marc Singer—while fleeing from a monster with which the dog shares a psychic link. Now Paul and the dog must team up with sympathetic psychologist Barbara (Tracy Scoggins) if they're going to survive! Sadly there's no skin in this game, but we do get a sexy scene where Marc Singer wears nothing but some tighty whities which he nicely bulges out!
