The problem is that miniature schnauzer fluctuate tremendously in personality, from merry and extroverted, to serious and introspective. Some individuals are incredibly terrier-like high-energy hectic, scrappy toward other canines, and stubborn. Other folks are so much calmer, easygoing, and sweet-natured that they may almost like another breed. With such a range in temperament, its hard to know very well what kind of miniature schnauzer youll finish up when fully developed.The miniature schnauzer likes his walks and needs a decent amount of exercise, but mostly he just wants to participate fully in the family. He or she makes an alert watchdog and may welcome strangers with enthusiasm or be somewhat standoffish, even suspicious, if not well socialized.
