A 27-year-old man threatened to kill his dad before throwing his father’s small dog across the room during a 90-minute drug and drink-fuelled rampage at their home.
Dale Rowland, 27, told his "prematurely frail" dad he would kill him before launching a violent tirade and stabbing a number of doors with a knife.
Derbyshire Crown Court was told Rowland and his father’s partner were outside when he grabbed her around the throat and pushed her against the wall.
Two days later, Rowland appeared to be under the influence of drink and drugs when he asked his dad for money, Derbyshire Live reports.
