Step 20: For a cleaner look, erase as much as you can of the initial guide lines. Don't worry about erasing all of the guides. It's okay to leave some behind. Re-draw any final sketch lines you may have accidentally erased.
Final Step: Shade your basset hound drawing for more detail. Use a medium value on the dog's head and ears. Leave a thin strip on the forehead blank. Draw the outline of the pattern on the head and then shade it in. Shade lightly at first and slowly build up the value. Use a dark value on the nose but leave a strip blank for shine. Add some spots on the dog's muzzle. Vary the pressure on your pencil to get different degrees of tonal value. Draw big, random splotches on the body and then shade them in. Your pattern can look totally different from this one. It's a good idea to use reference as you draw for an accurate depiction of a basset hound. If you have a pet basset hound or a similar breed, try to duplicate its coat markings on your drawing. For a more detailed guide on how to shade, check out this tutorial: How to shade.
Add some shadows all over the basset hound using a slightly darker value to give the figure more dimension and volume. Pick the direction of the light source when shading so that the shadows are consistent with it. Shading can be time-consuming, so be patient and take breaks. Don't forget to pause the video after each step to draw at your own pace. Add a cast shadow underneath to ground the dog so it doesn't appear to be floating.
