Step 6: Draw a couple of short lines below the head as guides for a bit of the dog's neck.

That's it for the guides! From this point on, press harder with your pencil for a more defined drawing.

Step 7: Lightly sketch the dog's eyes inside the head as two small circles. The eyes should be sitting on top of the horizontal guide line and on either side of the vertical guide line. When you get the position and size of the Labrador retriever's eyes right, darken the lines. The eye on the left should be a bit smaller than the eye on the right because the head is slightly turned.

As you darken the eye on the right, make the sides longer and pointier. For the eye on the left, only the right corner of the eye should be prominent because of the way the dog's head is turned. Add a curved line above and below each eye for extra detail. Break up these curved lines into short strokes for a fur-like texture.

Step 8: Inside each of the dog's eyes, draw a tiny circle to represent glare. You can draw an extra tiny glare circle inside the eye on the right for extra detail. Inside each eye, draw a small circle and shade them for the pupils. Don't overlap the tiny glare circles as you shade in the pupils. Use a dark value for the pupils but don't push down too hard on your pencil or you might tear the paper.

Draw a few more lines inside each eye to emphasize the shape of the eyeball. Draw a couple of curved lines inside each eye, near the bottom edge. The eye and eyeball on the left side should be narrower because of the way the head is turned. Draw a series of curved lines made up of short strokes above each eye to create the Labrador retriever's furry brows.

Step 9: Inside the circle guide for the Lab's muzzle, lightly sketch a small oval for the nose. Place this oval on the left side, right on the edge of the main circle that's a guide for the head. When you get the size and position of the oval right, darken the top edge first. Make the lines for the sides of the oval curve inward to create the nostrils. Make the tips of the curved lines darker and thicker to emphasize the dog's nostril openings.

Add a vertical line at the bottom that splits the Labrador retriever's nose lower section of the nose in half. The nostril on the right should be a bit bigger than the one of the left because of perspective. Don't make the nostrils too big, otherwise your dog might start looking like a pig! Use short strokes as you darken the bottom edge of the nose.
