Step 10: Draw the eyes inside the head. Use the construction lines as guides for placement. The shape of the eyes is basically a small arc with a line underneath it. Max's eyes should be very close together. They should be on top of the horizontal construciton line and on either side of the vertical line. The eye on the right should be bigger and wider than the one on the left because of the perspective.
Step 11: Inside each eye, near the right edge, draw a small circle for Max's irises. The iris on the right should be a bit bigger. Draw a tiny circle on the top left side of each iris to represent glare. Inside each iris, draw a smaller circle and shade it in for the pupils.
Step 12: Above each eye, draw a thick, curved line for Max's eyebrows. The eye on the right should be a bit bigger and longer than the one on the left because of perspective.
Step 13: Draw a big oval-like shape inside the muzzle for Max's nose. The top left side of the nose should touch the side of the muzzle. The right side of the nose should touch the initial circle. The shape of the nose is almost like an egg. Give it sort of a rounded point on the right side. The bottom edge of the dog's nose should be more flat than the top edge. Draw two small ovals inside the nose, near the bottom edge, for the nostrils.
Step 14: Use the initial curved line next to the head as a guide to draw Max's muzzle and mouth. Follow the basic path of the guide on the left side, and then curve the line to the right under the nose before it hits the bottom. The line should stretch far into the head, then curve up and almost touch the lower edge of the initial circle. When you get the shape of the mouth right, make the line thicker and darker.
