What Type of Dog Is Good for a Watchdog Indoors?

A watchdog alerts its owners when it sees a stranger approaching or something amiss, while guard dogs have the physical ability to stop an assailant from harming its owner. Some guard dogs such as Rottweilers and German shepherds also make good watchdogs, but may be too large for some indoor environments.

  1. West Highland White Terrier

    • Also known as the "Westie," the West Highland White Terrier may not look like the typical watchdog due to its small size, but looks can be deceiving. This strong-willed breed can be possessive of its home and will doggedly defend it. Always on alert, Westies will bark to warn of or ward off intruders. Not only is the Westie a good watchdog, but it is friendly, a great companion and good with children.

    Australian Sheperd

    • The Australian shepherd, or "Aussie," is also a great indoor guard dog, watching over the home and family. This loyal breed is smart and easy to train. Australian shepherds are also full of energy, so you will have to give them plenty of exercise outside the home. Be forewarned, though, that they are herding dogs, so they will most likely nip at the heels of running people.

    Chihuahua

    • Chihuahuas, the smallest breed of dog, make fantastic indoor watchdogs, especially for those living in close quarters or the elderly. These extremely smart pups are loyal, but they are alert, easily provoked and quick to bark if they sense intruders. This also means Chihuahuas are distrustful of people and animals they don't know, so there may be many false alarms.

    Boxer

    • Boxers, according to the American Kennel Club, need and desire human contact--especially from children--and they are fiercly protective, making them a great watchdog for families. This intelligent, powerful and clownish breed is one of the most popular in the U.S. They love to play with their family and they need to be exercised regularly out of doors.

    Poodle

    • Both the standard and miniature breeds of poodles make good indoor watchdogs. Exceptionally intelligent, the poodle has a protective nature and will alert its owners if it perceives trouble. This breed is eager to please and excels in obedience training. Its hypoallergenic coat makes it a good breed for those with allergies. The miniature breed is perfect for smaller living spaces such as apartments.
