Step 1: Outline Basic Shapes
Dog's Body and Head: Start with a large oval for the body and a smaller circle at the top right for the head.
Ears: Draw two elongated ovals on top of the head circle for floppy ears.

Step 2: Add Facial Details and Legs
Face: Inside the head circle, position two circles for eyes and a small oval for the nose. Add a curved line for a smiling mouth.
Legs: Draw four leg shapes extending from the body, using slightly curved rectangles for the front two legs and ovals for the hind legs.

Step 3: Define the Dog's Features
Tail: Add a long, wavy line extending from the back of the oval body to form a tail.
Feet: Round out the ends of the legs to create paws, adding small oval shapes for each paw.
Fur Detail: Use wavy lines along the ears and body to indicate fur texture.

Step 4: Add Shading and Depth
Body: Lightly shade the underside of the dog's body to give it depth.
Ears and Nose: Add shading on one side of the ears and the nose for dimension.

Step 5: Final Touches
Highlights: Place small highlights in the eyes to make them appear shiny.
Shadows: Emphasize shadows under the paws and tail to give the drawing more depth.
Accessory: Add a simple collar around the neck circle for an extra detail.
