The Killer Shrews (1959)

A disparate group are trapped on a remote island by a hurricane. On the island, a doctor works to make humans twice as small as we already are. This, apparently, will help prevent over population. Unfortunately, his experiments have also created some giant shrews. As the shrews run out of smaller animals to eat, they move in on the people in the house. Starring James Best, Ingrid Goude (Miss Sweden 1956), and Ken Curtis. A classic Sci-Fi horror movie filmed in Texas. Are those dogs dressed up as giant shrews?
