Add ears and a head.
Draw the legs.
They should not be connected to the head, they should be below it.
Draw the body, but DO NOT draw the bottom legs yet.
Now draw the back legs.
Make a little loop thing (I know XD) and a little oval-thing for the foot.
It's not a dog without a face! Give that cutie his face!
Now add that tail... He's gotta show us he's happy!
