Step 15: Use the lines on the right as guides to draw the shih tzu's first ear. Draw long strokes along the path of the guide to create the furry ear. Use shorter strokes for shorter fur. Add a few strokes along the edge of the initial circle on the left side for the visible part of the dog's other ear.
Step 16: Use the main circle as a guide to draw the rest of the shih tzu's head. Use quick, short strokes as you follow the basic path of the circle to create the furry shape of the head. Notice how the strokes change direction at the top before they meet the ear.
Add some quick short strokes above the shih tzu's eyes to emphasize the furry brow and forehead. Don't make the head too wide. Pay attention to the distance between the left edge of the head and the eye on the left. Draw a few strokes at the bottom to finish up the shape of the head.
Step 17: Use the second line from the left under the body as a guide to draw the dog's first front leg. Follow the path of the guide and lightly sketch the shape of the leg around it. When you get the shape of the leg right, darken the lines. Use quick, short strokes for the fur. The shih tzu's fur should be shaggy, so don't draw the individual toes, as the fur will be covering them. The shape of the leg should be wide at the top and gradually get thinner at the bottom.
Step 18: Use the line on the far left side as a guide to draw the second front leg the same way. Follow the basic path of the guide as you draw the shape of the leg around it.
Step 19: Use the line on the far right side as a guide to draw the hind leg that's on this side of the body. The top part of this leg is so wide that it actually overlaps the guide on the left. The lower half of the shih tzu's hind leg is thin compared to the top part. Remember to use quick, short strokes for the fur.
