Step 10: Inside the schnauzer's head, lightly sketch two small circles for the eyes. Use the initial lines as guides for placement. When you get the size and position right, darken the lines. Make the eye on the left a bit pointier on the sides. The shape of the eye should be similar to a little football. Draw a few lines around it for extra detail. Make the eye on the right a bit smaller and thinner because of the way the dog's head is turned.
Step 11: Inside each eye, off to the side, draw a tiny circle for highlights. In the middle of each eye, add a dot for the pupils. Shade the inside of the eyes but don't overlap the tiny highlight circles. Use a value that's slightly lighter than the value for the pupils. For a rounder look, use a dark value at the top of the dog's eyes and a lighter value near the bottom.
Above the schnauzer's eyes, draw two thick shapes that are made up of short strokes for the bushy brows. Use the initial lines and shapes as guides to help you place the bushy brows. The outer edges of each brow should curve downward a bit to create an arc-like shape. The brow on the right should be slightly narrower than the one on the left because of the dog's turned head. The tips of this brow should extend outside of the initial circle for the head.
Step 12: Inside the muzzle, near the top, lightly sketch a small oval for the schnauzer's nose. When you get the shape and size right, darken the lines. Curve the sides inward to create the nostrils. The nostril on the right should be smaller than the one on the left. Draw a vertical line between the nostrils. Make the bottom part narrower and use short strokes for the dog's fur.
Step 13: Below the nose, draw a series of short strokes for the fur-covered mouth. To the left of the dog's mouth, lightly sketch a series of short strokes toward the bottom of the initial circle for the mustache. Use the initial circle as a guide to draw this side of the mustache. When you get the shape right, darken the lines. To the right, use short strokes to draw the other side of the schnauzer's mustache the same way. Follow the edge of the initial circle as you draw the shape of the mustache.
Step 14: Along the bottom edge of the muzzle circle, draw short strokes for the beard. Draw a series of short strokes above the nose for the furry top of the muzzle. Use the top edge of the initial circle as a guide to draw the short strokes on the schnauzer's muzzle.
