How to draw a realistic dog nose

For this tutorial you will need the following;

○ Paper

○ Charcoal pencils 

○ Pencil eraser

○ White gel pen 

Let's get started!!!

 Step 1: Structure and sketch

Structure 

The first thing I like to start with and recommend to anyone drawing this is looking for lines and angles of the nose that I am working on. I like to view this as the structural map of a nose.
The most crucial angles to identify when drawing a dog or any animal's nose are:
○ The shape of the nostrils;
○ The size of the nostrils;
○ The size of the overall nose.

 Sketch

We can now start to make the nose look more natural. The trick with working with pencils is avoiding to go in dark at once hence it is important to keep the sketch lines light to avoid messing up our paper. Working light will help us whenever we need to erase or change a few things.


Step 2: Block in

Now the real deal begins, we are now moving on to shading. Before doing this though, we need to identify our light and dark shades. We are working on a 2-D surface but  trying to show something that has three dimensions.
Each one of the nose parts will have a different shade, depending on whether it is facing the light or not. Most of the times, the top of the nose will be very light and have a highlight. We can create this by lightly shading then erasing later on or we can simply leave it the white of the page. At this stage we also put the details on the nose using a graphite pencil. 

Step 3: Detail

In the third step, we are starting to add details and highlighting the lightest parts of our nose including the area just below the nostrils and above the nose (I used a putty eraser for this process). The key now is to add the little fur just beneath the nose. For this process we will use an eraser pencil or a tombow eraser. This will take some patience and some careful looking. 

Step 4: Final touch ups

In the last and final step I added more highlights on the top of the nose and on the nose itself, I used a white gel pen for the little highlights on the nose, a pencil eraser will work but not too well so I suggest using a pen considering how small the drawing is. Using an eraser may make you erase the shadows whilst trying to add highlights.

 

Good luck and keep drawing. Do not be discouraged if you don't see instant results. Patience is key in art...
