The Minnie Jack, as a Jack Russell Terrier-Mini Pinscher mix, is a small-sized, short-haired crossbreed with an athletic, lean yet muscular body, large ears, wedge-shaped head, and a long tail that normally curves upwards. Can be stubborn and dominant may need obedience training.

Extremely high-energy will require a great deal of exercise.Minnie Jacks are not recommended for families with children, as they may become too excited (and in turn, too rambunctious) around kids, and are not very tolerant of them. These excitable, outgoing little dogs are best suited for singles, couples, or seniors, and owners will need to spend a lot of physical (and emotional) energy with them. The Minnie Jack, a member of the Terrier group, probably originated during the designer dog breed explosion in the U.S.
