5. Miniature Schnauzer: The Mustachioed Watchdog

The Miniature Schnauzer combines the sturdy, fearless nature of a terrier with a highly obedient, eager-to-please temperament. Weighing 11 to 20 pounds, they are instantly recognized by their bushy eyebrows, wiry coats, and walrus-like mustaches.

Unlike many terrier breeds, Miniature Schnauzers were bred down directly from the Standard Schnauzer rather than British ratting terriers, which gives them a slightly more cooperative personality. They live 12 to 15 years and are deeply devoted to their families. Research from the Royal Veterinary College shows that Miniature Schnauzers are generally a robust and healthy breed, though they thrive best when integrated into the daily activities of the household.

You will appreciate their low-shedding coat, though it requires professional grooming or hand-stripping every few months to maintain its texture. Keep a close eye on their diet; Miniature Schnauzers are prone to gaining weight and developing painful bouts of pancreatitis if you feed them high-fat human foods.
