Rather than teaching this to individuals all of the time, I'm providing this basic guide for the public to use as a reference. I'm no expert, and I strongly encourage you to study real pictures of dogs to see for yourself their range of movement and structure.

This is, of course, a much simpler version of actual dog anatomy. As long as you know this much, you'll be fine. This isn't meant to be a scientific study. I haven't even used proper names because most of you would scratch your head if I told you to remember the 'os calcis' when drawing a hind leg.

The first image is the structure itself. I then roughly sketched in the shape of the body, and finally, added a bunch of extra fluff (which is probably a bit exaggerated).

Blue is where the main bones would be located.
Green indicates muscle.
Pink helps in pointing things out.

I've also shown common dog ears. For more realistic ear shapes, study photographs. Hope this helps some :]
