Summary:
Not a lot of problems regarding the overall shape and anatomy. Your neck was a touch too long and the head might be a touch too small/body too big. xD
The back feet I think had the biggest issues, it was pushed forward too much and looked like it was gonna break. An easy way to fix this is to make sure your lines stay straight when working with that part of the leg. :3
On the front legs, there's those weird little arm pads at the wrist of the arm. The dew claw should be right around that area too.
Overall very nice and try using references to get the small details down and you'll be a wolf expert. xD
