Start out with the basic shapes. Keep in mind that this figure will be mostly fur so don't worry too much about estimating the dog's size perfectly.
Now roughly sketch in the dog's outline, fur, and facial features. Keep your lines rough but not too rough. Just give yourself something to work with.
Now you can start outlining and defining around the head. A dark outline or background will really make the dog's white fur pop out. You should only have to use your dark pencils on the eyes, nose, mouth, outline, and later on the ground. Everything else will either be a value of grey or white.
Finish up the outline around the dog. You can also hint at the ground during this step. Don't get too caught up about outlining the fur perfectly yet.
Now you can start adding more detail and shading to the face. Notice how I used my lines to avoid having to draw each strand of hair in detail. Just follow the directing that the fur would naturally flow with your pencil strokes. Keep the same thing in mind when outlining the fur.
Make your way straight down the dog's front legs. The fur shading is really best done with a pencil or multiple pencils in the H range. It's still possible using a regular HB pencil however your lines will appear darker.
This step involves sketching in the fur for the rest of the body. Pay attention to the fur direction and keep it light. This is the last step before beginning the finalization of the drawing.
Alright, compare this step with the previous step closely. Notice how this step is all about final details. Make your outlines as dark and crisp as possible and smooth out the fur. Don't use a tortillion for blending and smoothing, use either your finger or tissue paper instead. You want to be gentle so that you don't rub away all of the detail from the previous steps!
Continue making your way around the dog working from the outline in. Notice how you can barely see the sections of fur but that they ARE there. A kneadable eraser also comes in handy hear for erasing and blending.
Finish up the drawing by completing the outline you can then add a ground or a background if you so desire. I think this would be a good practice tutorial for anyone who wants to work on their lighter shading since dark shading is often easier than darker shading. I hope this was helpful and informative and encourage you to check out my other dog tutorials too.
