Some things:

• The muzzle is longer and the "forehead" is smaller.
• The eyes are much smaller.
• Wolves don't really hold their necks up high. They kind of slouch forward.
• Wolves generally have their tail down when they're resting.
• The legs you drew aren't too bad. The bottom part of the back legs should be a bit shorter though; their length should make up about a third of the height of the leg/butt area.
• I know it's your style but the paws could be a little more defined and separate from the legs.

I'm guessing that you're trying to draw in a cartoon style and not realistically. If that's the case, just try to incorporate some of these things into the style. Otherwise, trying referencing from pictures to get a realistic look. A good tutorial for drawing wolves is this.

I hope this helps!
