A man in a brilliant red military coat stands upright against a dark, indistinct background, his figure illuminated by a strong, frontal light that picks out the crisp white of his collar and breeches. His left hand holds a black bicorne hat trimmed in gold, with a yellow circular emblem on its side, while his right arm extends outward, lightly grasping a slender black cane or riding crop. At his feet, a large dog with a mottled white and black coat sits obediently, gazing up at its master, its form rendered with loose, energetic brushwork that contrasts with the sharper contours of the man's attire.

The man’s expression is composed and reserved, his gaze directed outward, with slightly parted lips and a dignified bearing that is reinforced by the upright posture and the formal cut of his uniform. Gold trim and buttons catch the light along the edges of his coat, and a decorative sash and sword hang at his left hip, their metallic highlights painted with swift, fluid strokes. The background is a deep, nearly featureless brown-black, with only faint suggestions of landscape or shadow, focusing attention on the sitter and his dog.

The ground beneath them is painted in earthy tones, with the artist’s signature and inscription visible in the lower left corner, integrated into the painted surface. The composition is vertically oriented, with the man occupying the center of the canvas, his vivid coat forming the dominant color accent against the subdued setting. Brushwork varies across the surface: the face and hands are modeled with careful, blended strokes, while the background and the dog’s fur are treated with broader, more expressive marks. The artist’s handling of paint, especially in the textured surface of the background and the lifelike modeling of the sitter’s face, demonstrates the technical range that characterizes Goya’s mature portraits.
