Step 6: Draw a small U-shaped line on the inside of the dog's head as a guide for the ear.
That's it for the initial sketch! From this point on, press harder with your pencil to get a more defined sketch.
Step 7: Draw the labrador's eye. It's basically a triangle pointing left. Draw a circle inside of it as the pupil and shade it in.
Step 8: Tighten the shape of the dog's ear by using quick, short strokes to represent fur.
Step 9: Draw the labrador retriever dog's nose as a square with rounded corners on the tip of the muzzle. Inside that shape, draw an oval and shade it in for the nostril.
