Noob would appreciate help

I am starting to use Blender and I was attempting to make use of a wiki-tutorial. At first it seemed helpful, but I got stuck at the point where you are supposed to create a 3-D dog from the pictures it gives you as it gives little instruction as how to do so. If you have encountered this guide and know how to create the 3-D dog once you have the images in Blender please tell me.

Add a Mesh >> Plane. Delete three vertices, select the remaining one then use Ctrl-LMB (Ctrl-LeftMouseButton) to extrude the following verts. If you didn’t place the original vert over the starting one go back and delete it. Tab into Object mode when you’re done and click “Center New” in F9 buttons to recenter your Object Center.
