In Portræt af en lille pige med en hund, we see a young girl seated with a small dog in her lap. The colors are soft and warm, with gentle hues of pink and cream dominating the girl's dress. The background is a muted landscape, which helps to focus attention on the figures.

The girl's expression is calm and serene, suggesting a bond with her pet. This painting is executed in oil on canvas, a common medium for portraits of the time. The brushwork is smooth, allowing for fine details in the girl's features and the texture of the dog's fur. The dimensions are approximately 60 x 80 cm, making it a medium-sized portrait.

The composition is balanced, with the girl and dog positioned centrally against the soft backdrop. Jens Juel was a prominent Danish painter known for his portraits during the Danish Golden Age. This work reflects his ability to capture the innocence of childhood and the affection between a child and her pet. An interesting fact about this painting is that it exemplifies the domestic themes prevalent in Juel's work, highlighting the importance of family and companionship in 18th-century Danish society.
