Step 6: Below the nose, draw a long, horizontal line for the first part of the muzzle. Curve the ends of the line upward to create the sides of the wolf's muzzle. The line should curve to just above the nose. Don't curve it too close to the eyes.
Step 7: Draw a line between the eyes to emphasize the furrowed brow. Add a couple more curved lines for the wrinkles on the sides of the muzzle. These wrinkles help emphasize the cartoon wolf's snarl/growl.
Step 8: Under the muzzle, on either side, draw a V-shaped line for the wolf's long canine teeth. You can make these teeth longer or shorter if you'd like but leave room in the middle for more teeth.
Step 9: Between the canines, draw a short, horizontal line for the gums. Below the gums, draw a row of small, v-shaped lines for the wolf's front teeth.
Step 10: Under each canine, draw a short, vertical line for the sides of the mouth. In the middle, draw a curved line with a line in the middle for the wolf's tongue.
