Trace over the vertical line extending from the nose to the mouth. Sketch fur over the outlines going down each side of the mouth. Trace over the outline for the top lip too. Then with a 6B pencil, shade the inside of the mouth very dark.

Similar to the spot above the nose, this dog has a large spot or birthmark covering the area between the nose and mouth. Sketch its outline as well as some texture details on each side of the vertical line joining the nose and mouth.

To shade this spot, I’m starting with a general base layer of diagonal strokes to cover the entire surface. Then, I’m going over it again with a second layer of shading. However, this time my strokes are shorter to more closely resemble hair. Finally, use darker tones to sharpen the edges just under the nose and around the mouth.
