Dogs are drawn here as somebody's dog, not a breed chart. Bim the German shepherd. A girl and her best friend. A boy who is clearly the dog's, rather than the other way round. One pair sunbathing with no intention of moving.
Short coat, long coat, ear fringe and wet nose all take different treatment, and the pre-shaded grayscale marks where each one catches the light.
A popular one to color as a portrait gift, which is something buyers tell me far more often than I expected when I started drawing them.
