There are several warnings that occur when a Hound attack is imminent. * You will begin to hear barking and growling that becomes louder and more frequent as they get closer. * Your character will say phrases like, "Did you hear that?", to alert you. (See character quotes here.) On default settings, the first attack will consist of 2 Hounds and you will have 2 minutes before the Hounds appear. Hound attacks will not occur until at least Day 6.
