Step 6: Below the circle on the left, draw a line that's similar to a flat letter U as a guide for the dog's font leg. Add a similar shape to the left as a guide for the other front leg. Don't make these guides too long.
Step 7: To the right, add the guide for the Scottish terrier's hind leg by first drawing two short, vertical lines. Close off the guide by drawing a flat line at the bottom.
Step 8: Draw a series of lines that connect the major shapes to finish the guide for the dog's body. Draw a short line on the top, right side of the body as a guide for the Scottish terrier's tail.
That's it for the guides! From this point on, press harder with your pencil for a more defined drawing.
Step 9: Inside the head, lightly sketch a small circle for the eye. Use the initial line to guide your placement. When you get the size and placement of the Scottish terrier's eye right, darken the lines. Inside the eye, draw a tiny circle for glare or highlight and a dot in the middle for the pupil. Shade the eye except for the tiny glare circle. As you shade the eye, use a dark value at the top and a lighter value at the bottom for a rounder look. Add a few curved lines to the eye for the eyelids and corners. Add a few more lines higher up for a bit of fur.
