Step 6: Draw two lines below Scooby-Doo’s head for his neck.
Step 7: Below Scooby-Doo’s neck, draw two curved lines for his collar. Under his collar, draw a diamond shape as a guide for his dog tag.
Step 8: Now you’re done with the initial sketch! You have the basic Scooby-Doo shape, so now go in and tighten your drawing. From this point on, press harder with your pencil in order to get darker lines and a more defined sketch.
Step 9: Darken Scooby-Doo’s eyes. Inside each eye, draw a circle for his pupil and shade it in. Above each eye draw a small curved shape for Scooby-Doo’s eyebrows. Draw a curved line under the left eye for detail.
Step 10: Using the initial shape of the muzzle as a guide, draw the bridge of Scooby-Doo’s nose, which begins between his eyes and then curves up slightly. At the end draw his nose, which is similar to an upside-down triangle with rounded corners.
