Step 20: Use the remaining lines as guides to draw the rest of the golden retriever's body. Draw quick, short strokes along the path of the guides to create a furry texture. Use slightly longer strokes along the underside of the body for longer fur. For the top part of the dog's body, simply darken the outer edges of the initial guides. Use the line on the right as a guide to draw the tail. Draw the tail around the guide. Make the top part straight and the use quick, short strokes for the long fur at the bottom.
Step 21: 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: Add some shading to your golden retriever's drawing to give it more dimension and volume. Use a dark value for the dog's nose. Pick the direction of the light source when shading so that the shadows are consistent with it. Vary the pressure on your pencil to get different degrees of tonal value. Continue shading until the entire body has the appropriate shadows.
Add a cast shadow underneath. This helps ground the dog so it doesn't appear to be floating. Use a darker value near the middle of the shadow and a lighter value along the edge for the shadow's diffusion.
You can add even more value throughout your drawing for extra detail. Golden retrievers don't have any pattern on their coats like spots or stripes, so just add a medium value to the whole body. Use shorter stokes when you add the value to the head as opposed to the longer strokes you will use for the body. As you add the value, separate each individual stroke a bit so that the white of the paper comes through and creates a furry-looking texture.
Use strokes that go in the general direction of the fur as you add the value. The strokes on the golden retriever's chest should have a vertical orientation, while farther back along the body, the strokes should be horizontal. Don't worry about shading too smoothly. The rough value gives the dog's coat a furry texture. Shading can be time-consuming, so be patient and take breaks. If you have a pet golden retriever or a similar breed, try to duplicate its fur on your drawing. Remember to pause the video to draw at your own pace.
