Hi,thanks for the review! What actually happens is that you take your dog fishing, but you're not quite right in the head, so you think it's talking to you. After several trips, the dog turns evil, and you decide to kill it. When you do, you snap back to reality and end up killing your dog, who was actually normal. You can tell because in the scene where the dog is lying down, it's normal and not covered in blood. The same thing happens in the other scene.
