Step 10: Lightly sketch an oval inside the small circle, close to the bottom edge, for the wolf's nose. When you get the placement of the oval right, darken the top edge. Inside the oval, on either side, draw a small circle and shade it in for the nostrils. Split the bottom edge of the nose using a short line and add a few quick, short strokes along the bottom for fur.
Step 11: Use the small circle as a guide to draw the top part of the growling wolf's muzzle. Darken the lower edge of the circle to create the bottom part of the muzzle. Draw a series of short curved lines above the nose to indicate the wrinkled skin. The lines should curl in from the sides to the top of the nose. Most of the wrinkles should stay within the small circle, but you can add a few outside too.
Step 12: Draw the teeth below the muzzle but leave a small space between them to indicate the gums. Start by drawing the long canine on the side as a triangle- like shape, then add the smaller teeth in the middle. There should be six teeth between the long canines on the sides, but you can draw only four to make it easier. The teeth should get progressively smaller until they reach the middle, then they should start increasing in size again. The shape of the teeth should be similar to traingles but with a slightly rounded tips.
Step 13: Draw the bottom row of teeth a little bit higher than the lower edge of the initial circle. First draw the long canines on the side, then add the smaller teeth in the middle.
Step 14: Now draw the rest of the mouth. First draw a curved line under the top row of teeth for the tongue. Then follow the basic path of the U-shaped guide to draw the outer edge of the mouth. Darken the U- shaped line to create the lower jaw and chin. Use quick, short strokes to indicate fur.
