My handwriting looks terrible here on oekaki (laggy tablet :<), so I'll explain here some things:
A wolf is much taller, and it also needs a neck!
You can't start immediately with the legs after the head, a wolf has a neck between the frontlegs and the head ^^
The tail is usually just hanging down.
And if you draw the muzzle from the side, you can't put both eyes on one side (then the wolf would have 4 eyes if there are 2 on each side xD)
Oh well. I'm bad at explaining... sorry.
Edit: And your wolf needs of course more fur (otherwise it would look so... naked :'D
Maybe this tutorial can help you better:
