EDIT: Just to make this clear. THIS IS HOW I (USED) TO DRAW SNARLING WOLVES. It is not correct, and the anatomy is COMPLETELY flawed in some aspects. Use at your own discretion! (keep in mind this tut was made way back in 2006)
If you want to draw anatomically correct growling wolves, GO LOOK AT A PHOTO. Its much better than learning from a flawed tutorial.
Sorry for the crappiness x_x;
Some people asked for one, so I did.
Be aware that:
This tutorial is flawed, this is how I draw things, the anatomy is not perfect. So... cha dude.
If it does manage to help, it'd be cool to see what you guys come up with x);
So tiiirreddd... xD
