FML... there are dogs in this horror movie so it's just about mandatory they resort to the "kill the dog" trope. About the 57:00 mark, a dog is chasing the idiot father when the son is able to call the dog off his father, but instead of leaving things as they are, the stupid dad goes after the dog with a chain saw and decapitates the poor animal. Skip to 58:18 to not waste your time on watching this bit of lazy writing.
