Step 20: Draw the spaniel's other front leg around the guide line on the left the same way. Don't draw the top part of the leg, as it will be mostly blocked by the body.
Step 21: Use the line on the right as a guide to draw the cavalier King Charles spaniel's first hind leg. Lightly sketch the shape of the leg around the guide. Make the top part of the leg wide. When you get the shape right, darken the lines. Use a series of short strokes at the top to represent fur. Add a couple of curved lines at the bottom to separate the dog's toes.
Step 22: Use the last line under the spaniel's body as a guide to draw the other hind leg the same way. Draw the shape of the leg around the guide line. Don't draw the top part that will be hidden behind the dog's body.
Step 23: Use the remaining shapes as guide to draw the rest of the cavalier King Charles spaniel's body. Draw a series of short strokes along the outer edges of the initial guides to create the shape of the furry body. Use longer strokes along the underside of the dog's body for the shaggier fur found there. The fur at the top lays flat, so just darken the top edge of the initial guides.
Step 24: Draw a couple of wavy lines around the guide on the right for the spaniel's tail. At the bottom, draw a series of short strokes for the furry tip.
