Guard dog breeds
A guardian isn't an aggressive dog: it's a dog that takes seriously who comes in and who doesn't. These 11 breeds score 4 or 5 in guarding instinct.
How this list was built
The rule, out in the open
- Guarding instinct ≥ 5/5
11 of 30 directory breeds qualify · 19 don't · 0 have no data for a field in the rule (left out, named below)
The numbers come from the Lord Chucho deck: the scale published by the AKC and the books in our library, with a citation on every bar. Where there's no data, there's no breed: we'd rather leave the gap than make it up.
High guarding instinct demands a present owner: socialization from puppyhood and training. A guardian without guidance is a problem, not a bodyguard.
