This image in a naive style is meant to represent the love a young woman has for an animal. The unusually large bust of the young woman is there to suggest a protective side, just like the positioning of her arms, which enclose the dog.
The animal, in turn, has the smooth, shiny and clean coat of a house animal. Chubby baby, he lets himself be caressed by the one who adopted him. His silky and cottony coat symbolizes the softness of his body, of his character, but also of the scene and his life.
