The dog goes to the crazed stepfather while he weilds a knife. Squirms and is eventually saved by the daughter coming home. But it does look like a close call.
First two minutes, the stepfather puts on contacts up close. Not mutilation but if you don't like eye stuff, you probably won't like it. Nothing gorey or anything, just contacts. 1:04:56 he removes them
Around 45 minutes in Jerry kills the therapist and in order to avoid suspicion he sets it up to look like an accident. He sets up the car to fall of the cliff and catch on fire. No one in the car is alive when it crashes.
