MST3K Ep. 407 - "The Killer Shrews"

(Short: Junior Rodeo Daredevils) A hunky skipper makes a delivery to a small island, and learns that the inhabitants include heavy-drinking scientists doing genetic experiments resulting in a pack of omnivorous giant shrews (dogs with attached accessories). In the short, old-timer Billy Slater, a cowpoke, straightens out some wayward kids by making them put on a small-time rodeo.
