Step 15: On top of the greyhound's head, draw a wavy line for the top part of the other ear peeking out from behind.

Step 16: Use the second line from the left as a guide to draw the first front leg. Follow the guide and lightly sketch the shape of the leg around it. Bend the shape of the leg where the guide bends to indicate the joints. When you get the shape of the leg right, darken the lines. The greyhound's leg should be wide at the top and gradually get thinner toward the bottom.

Where the leg bends, draw a small bump on the right side to emphasize the joints. Draw the dog's paw at the bottom using a series of short, curved lines to split the individual toes. At the tip of each toe, draw a small, triangle-like shape for the nails. The fourth toe will not be visible because of the angle of the body. Add a few lines inside the leg to emphasize the muscle structure.

Step 17: Use the line on the far left side as a guide to draw the greyhound's second front leg the same way. First sketch the shape of the leg lightly around the guide. Then, when you get the shape right, darken the lines. Use the first leg as a template. Add the claws at the bottom. The right side of the leg will be hidden by the first leg.

Step 18: Use the line on the far right side as a guide to draw the hind leg that's on this side of the body. Sketch lightly at first. When you get the structure right, darken the lines. Notice how much wider the top of the greyhound's hind leg is compared to the front leg. The leg should slope toward the right, then bend at the joint and angle downward.

Use a couple of curved lines at the bottom to draw the dog's toes. Then add the small triangle-like nails at the tip. As you draw the shape of the leg, make sure it gradually gets thinner toward the bottom. Add a few lines inside the leg to emphasize the muscles and tendons.

Step 19: Use the last line under the body as a guide to draw the other hind leg the same way. The top part of this leg starts way at the top, below the small circle for the body. A big portion of the top of the leg will be behind the greyhound's other leg, so don't worry about drawing it. Add the paw, toes and claws at the bottom using curved lines.
