To draw this Boston Terrier Dog step by step, follow along with the video tutorial below and pause the video after each step to draw at your own pace. You may find it easier to follow the step-by-step drawings below the video. The new lines in each step are shown in red, so you'll know exactly what to draw next. You may want to open the video in a new tab and use both drawing methods. Take your time and draw at your own pace.

The Written step-by-step video tutorial:

For the first few steps, don't press down too hard with your pencil. Use light, smooth strokes to begin.

Step 1: Draw a circle near the middle of the paper as a guide for the front part of the Boston terrier's body. To draw the circle, make four marks to determine height and width. Then connect the marks using curved lines. Sketch lightly at first so that it's easy to erase if you make a mistake. If you're struggling to draw the circle, just trace the outer rim of a circular object like a coin or a lid. For a more detailed guide on the different ways to draw a circle check out this tutorial: Four simple ways to draw a circle.

Step 2: To the right, draw a circle that's about half the size of the first one as a guide for the back portion of the dog's body. Use the four-marks method to draw this circle too. Don't draw the circles to far apart or the Boston terrier's body will be too long.

Step 3: On the top, left side, draw yet another circle as a guide for the Boston terrier dog's head. The size of this circle should be about halfway between the first and the second circle. The edges of the circles on the left should touch. If these circles are too far apart, the neck will be too long.

Step 4: Draw a horizontal line across the head as a guide to help you place the Boston terrier's facial features later on. On the top, left side, draw a smaller, curved, vertical line for another construction guide.

Step 5: On the bottom, left side of the Boston terrier's head, draw a small circle as a guide for the muzzle. The top part of this circle should overlap a bit of the horizontal guide, and the bottom should overlap a bit of the head circle.

Step 6: On top of the head, draw two small, triangular arcs as guides for the Boston terrier dog's ears. Make the top parts round, not pointy. The ear on the left should be smaller than the ear on the right.

Step 7: Under the first circle, draw two long, vertical lines as guides for the front legs. Pay attention to the length of the legs in relation to the Boston terrier's body. Bend the lines to indicate the joints.

Step 8: Under the second circle, draw a line that slopes to the right before angling down as a guide for the first hind leg. To the left, draw a line that curves to the right and then angles down as a guide for the Boston terrier's other hind leg.

Step 9: Draw two short lines that connect the circles on the left to form the guide for the neck. Draw two longer lines that connect the circles on the right to finish the guide for the Boston terrier dog's torso.

That's it for the guides! From this point on, press harder with your pencil for a more defined drawing.

Step 10: Inside the head, lightly sketch two small circles for the dog's eyes. Use the initial lines as guides for placement. When you get the size and position right, darken the shapes. The eye on the left should be smaller. Make the sides of the eyes pointier as you darken the lines. Draw a few short, curved lines around the Boston terrier's eyes for the eyelids and some wrinkles.

Step 11: Inside each eye, off to the side, draw a tiny circle for highlights. In the middle of each eye, add a big dot for the pupils. The pupil on the right should be bigger. Shade the rest of the Boston terrier's eyes but don't overlap the tiny highlight circles. As you shade the irises, use a value that's dark at the top and light at the bottom for a more round look.

Step 12: Inside the muzzle, near the top, lightly sketch a small oval for the Boston terrier's nose. When you get the shape and size right, darken the lines. Curve the sides inward to create the nostrils. The dog's nostrils are basically two small slits. Add another small slit between them, on the bottom. Make the bottom of the nose pointier than the initial oval and darken the top edge.

Step 13: Draw a line under the nose that angles to the left for the first part of the dog's mouth. Pay attention to the length of this first line and the way it angles downward. From under the nose, draw a longer line that curves to the right for the other side of the mouth. Draw a curved line close to the left edge of the small circle for the side of the muzzle. Curve the Boston terrier's muzzle line up toward the mouth. Add a short line on the right side of the mouth for the loose skin.

Step 14: Draw a couple of short, curved lines above the nose for some wrinkles on the muzzle. Under the mouth, draw a series of short lines that slope to the right for the chin and some wrinkles. Add a few more short lines above the mouth for more wrinkles on the Boston terrier's muzzle.

Step 15: Darken the arc on the top, right side of the head for the Boston terrier's first ear. Inside the shape, along the bottom, draw a series of short, curved lines for the inner structure of the ear. These lines don't have to be perfect. Draw longer lines on the edges of the shape, near the top.

Step 16: Use the arc on the left as a guide to draw the Boston terrier's other ear the same way. Don't draw as many lines for structure along the bottom because the dog's head will be partly blocking the ear.

Step 17: Use the big initial circle as a guide to draw the rest of the dog's head. On the left side, draw a wavy line that's closer to the eye to make the shape of the head narrower than the circle. Draw a short, curved line over each eye to emphasize the thick brows. Add a few more short lines within the Boston terrier's head to give it more shape and structure.

Step 18: Use the second line from the left as a guide to draw the first front leg. Follow the path of the guide and lightly sketch the shape of the dog's leg around it. The top part of the shape should be wide and the bottom narrow. Bend the leg to indicate the joints. At the bottom, draw a couple of curved lines with small, triangular shapes on the tips for the toes and nails. Darken the rest of the Boston terrier's leg. Keep the edges of the shape close to the guide so that the leg isn't too wide.

Step 19: Use the line on the left as a guide to draw the dog's other front leg the same way. This leg should look similar to the first one, only smaller. Sketch lightly at first as you draw around the guide. Bend the leg near the bottom for the joints. When you get the shape right, darken the lines. Use a couple of short, curved lines at the bottom for the Boston terrier's toes and tiny triangular shapes for the nails. A portion of this leg at the top will be behind the body.

Step 20: Use the line on the far right as a guide to draw the first hind leg. Draw this leg the same way. Follow the path of the guide and lightly sketch the leg around it. This leg should be wider at the top than the front legs. The top should also slope to the right. Curve the lines near the middle for the joints. When you get the shape of the Boston terrier's leg right, darken the lines. At the bottom, add the toes and nails using short, curved lines and tiny triangular shapes.

Step 21: Use the last line under the body as a guide to draw the Boston terrier's other hind leg the same way. Lightly sketch the leg around the guide and only darken the lines when you get the shape right. Add the toes and nails at the bottom like before. The top part will be hidden behind the dog's body.

Step 22: Use the remaining lines and shapes as guides to draw the rest of the Boston terrier's body. Simply darken the outer edges of the initial lines to create the shape of the body. Curve the line at the bottom for the chest. Don't overlap the legs that are on this side of the body. On the top, right side of the body, draw a couple of short, curved lines for the dog's curly tail.

Step 23: 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: Outline an area around the Boston terrier's eyes, chest and legs that will separate the classic black and white markings. Use a dark value to create the black markings on the body. Add the value lightly at first and slowly build it up. Vary the pressure on your pencil to get different degrees of tonal value. This is an easy drawing to shade because you don't have to worry about fur. Just fill in the areas with dark value. Adding the value can still be time-consuming, so be patient and take breaks. Use lighter value under the dog's nose. For a more detailed guide on how to shade, check out this tutorial: How to shade.

It's a good idea to use reference as you draw for an accurate depiction of a Boston terrier. If you have a pet Boston terrier or a similar dog breed, try to duplicate its pattern on your drawing. Using a light value, add some shadows to the white areas of the body to give the figure more volume. Add a cast shadow underneath to ground the dog.
