Shih Tzus are bred to be lap companions, but that doesn't mean they can't have a tough, commanding name. Unisex tough names work especially well for these small dogs because the contrast between their delicate size and a powerful name creates memorable personality. These names suit dogs with confident, spirited temperaments—the Shih Tzu that barks at strangers, demands respect in the dog park, or just has an outsized attitude. Whether you want something edgy, no-nonsense, or unconventionally bold, this list focuses on genuinely tough names that transcend gender stereotypes and fit a dog with attitude.

What makes a name 'tough' versus just strong or bold?
Tough names typically evoke power, danger, authority, rebellion, or edge. They include weapon references (Blade, Arrow), military/action terms (Gunner, Ranger), mythological warriors (Orion, Titan), or defiant attitudes (Rebel, Rogue). Bold names can be tough, but tough names specifically convey an attitude of fearlessness or force.
