Figures are typical ranges and averages from published references. Individual dogs, and different lines, vary.

Versatile, trainable and widely available, with big differences between lines. Fits active families who can supply daily activity.

A heavy, confident guardian type that tends to be calmer than the herding breeds. Fits experienced owners with space and a firm, fair style.

Athletic and people-oriented. Fits households where someone is home often, since many dislike long absences.

A big working breed with a demanding coat and mind. Fits owners who enjoy grooming and training projects.

The most intense on this list. Fits very active, experienced handlers rather than most first-time families.

An Italian mastiff-type guardian and the heaviest here. Fits owners with room, strength and a plan for insurance and rules.

It cannot tell you how a particular dog handles children, noise or strangers. That is why the criteria page matters more than any breed row.

Why do lifespans differ between sources?

Studies sample different populations and lines, so averages differ. Treat them as ranges, not promises.

Should I choose by size?

Size affects your space, your insurance and how easily you can control the dog, so it deserves a place in your decision, but not the top one.
