Grandpa Earl Fell Asleep in the Hammock. Domino Took the Night Watch, in Daylight.

Strung between two sturdy tree trunks, the rope hammock sways ever so slightly, and Grandpa Earl is fast asleep in it. His head rests on a folded grey blanket, white mustache drooping, arms relaxed over his fishing vest, and his bare legs stretched out in the afternoon shade. Right beside the hammock, Domino sits upright on a blanket of his own, harlequin coat bright against the grass. He isn't sleeping. Instead, his ears are perked, head turned toward something in the yard, keeping a watchful eye on the neighborhood while his favorite person catches up on rest. Flowerpots, a cooler, a watering can, and a pair of boots dot the patio behind them.

Great Danes were historically bred as hunting and guard dogs, and while today's Danes are usually friendly and gentle, many still have a natural watchfulness. They're often alert to strangers and will let their family know when something seems unusual, typically with a deep, impressive bark. That protectiveness is generally mild and easy to manage with good early socialization, which helps a Dane learn that visitors, delivery people, and other dogs are nothing to worry about. Meeting new people and places as a puppy builds a calm, confident adult.

Earl can doze as long as he likes. With Domino on watch, the hammock may be the safest spot in the whole neighborhood.
