Best guard dogs
It’s important to distinguish between a “guard” and a “watch” dog. The Lassa Apso was bred to be a temple guard dog, but is a tiny, pampered-looking pooch. Conversely, the Cane Corso is all aggression and a difficult canine to train. The traits you want to look for in an excellent guard dog aren’t necessarily size-related, but treat with their temperaments. Guard dogs tend to be shepherding or herding breeds, and possess a slight reticence or alertness towards those not a part of their defined Pack—generally a result of many generations of breeding for guarding flocks from predators and poachers.
