Let us meet 7 fearless guardians that prove big hearts often come in small packaging.
Best Small Dog Breeds Choices for Watchdog Duties
1. Miniature Pinscher

5. Scottish Terrier
This breed was given the name in 1879. However, it has other names, such as the Hard-Coated Scotch Terrier, the Aberdeen Terrier, and the Die-Hard or Wire-Haired Terrier. Its ancestry goes back to the Highland Terrier. It was originally developed as a working dog, as reported by Purina.
The Scottish Terrier has a full beard, a thick moustache, and prominent eyebrows, giving it an authoritative appearance. These unique features also protect the face from external stimuli, such as dirt, debris, and predators’ attacks. The heavy-boned, muscular build gives it physical durability.

It has much larger teeth compared to its size because of a genetic deformity. It moves faster because of the silky white double coat that protects it from the elements. It always looks for the slightest sound to analyze and then reacts. The dog has strong territorial and protective instincts.
