Step 1: Start by drawing the head, making it vaguely shaped like two triangles with the point on the top one facing away from the other one leaving a gap opposite the point on the bottom triangle.
Step 2: Next draw in two circles, one inside the other for the eyes near where the two triangles meet.
Step 3: Then draw the opening for the nostril in between the eye and the point of the triangle.
Step 4: Next draw in the mouth with a hook at the end near the opening between the triangles.
Step 5: Then draw the body and curled tail leaving a space for the belly and the legs.
Step 6: Next draw the front and back legs and feet with claws.
Step 7: Then add in the belly and other legs.
