A Scottish terrier is a small and sturdy little dog. It has an odd rectangular-shaped head and wiry hair covering a soft undercoat. This dog is a good subject for a drawing because of its peculiar looks. Scottish terriers have to be professionally groomed, which enhances their odd, yet photogenic appearance. A Scottish terrier's fur is its main feature and makes this breed easy to recognise in a drawing.
Gather some reference images showing a clear view of the Scottish terrier from various angles, including close-ups. Place them near you, so you can see them as you draw. Select one of the images with a good side-view; draw the entire dog in this position. Examine the images so that you become familiar with the shape and character of the dog.
Draw the outline of the dog, starting with the rectangular-shaped torso. Draw the horizontal line for the back, the short-haired tail and the long flared-out hair on the underside. Draw wavy hair lines to match the length of the dog's hair. The best way to draw fur is to draw parallel lines going in the direction of fur-growth on the dog. Blend with a chamois and add more lines to complete the illusion of fur. Depending on the dog, the hair may come down all the way to the ground, covering the paws in some cases.
Draw the legs and paws, including the toes and claws. Note that the front legs and paws look bigger than those in the back. Shade the legs and paws using short lines and blend them with the chamois. Erase any smudges when finished with the legs and add a few more hair lines for detail.
Draw the neck and the outline of the head. Note the odd shape of the rectangular head due to the long hair on the muzzle. Fill in the muzzle area with more hair lines showing the hair extending down below the muzzle. Draw the hair originating from the top, behind the nose.
Draw the fur lines keeping in mind the direction in which they naturally grow. Use dark and light lines to create depth in the dog's hair, especially in areas where it is long and fluffy. Shade repeatedly as you add more layers of hair.
Detail the triangular ears of the dog. Shade the inner ears dark, with a lighter area near the outer edge. Shade the outside darker and fill in the general ear area with short fur lines. Draw the hair as it grows out beyond the outline. Keep layering with short lines until the ears blend in with the rest of the head.
Detail the nose at the end of the muzzle, including little circles for the nostrils. Shade the nose but keep a tiny white dot near the tip to simulate a reflective gleam. Note that the longer hair on the muzzle appears right behind the nose.
The eyes are like little shiny black buttons on the sides of the head. Erase any shading in the small spot where the eyes should be. Shade in the eye again, leaving a small light circle around them. This will add realism. Create a small white dot in the upper portion of the eye with the point of an eraser as a reflective highlight.
Determine the direction of the light source and shade any areas facing away. Keep those areas facing the light correspondingly lighter. Use a chamois to blend dark areas into lighter areas of the dog. Draw more hair lines to fill out the fur coat of the dog once you have finished blending.
Clean any smudges with the eraser.
