This coloring page features a stunning Doberman. The large and muscular dog has a sleek coat of black, complemented by tan markings around the face, chest and legs. A powerful and athletic breed, the Doberman is known for its intelligence, alertness and loyalty to its family - making it an ideal guard dog. To bring this beautiful image to life, I would color the Doberman black, with a tan hue for the markings on the head, chest and legs. The eyes and nose could be a deep brown, with some white around the eyes, giving it a friendly and alert look. For the background, I'd go with a contrasting light colour such as sky blue, to make the Doberman really stand out.
