Can anybody name the film?

Can anybody name a film I watched a few years ago it may be The Twilight Zone or Tales From The Crypt. It was probably 70s or 80s and it was set in short stories. I vaguely remember one of the tales was of a woman in her home at Christmas listening to the radio and she hears of an escaped mental patient and hey what do you know he turns up at her house. Another one was a guy being chased through a barb wire corridor by a german shepherd dog I think he was an evil old persons helper. Can anyone shed any light?
