Really, you pretty much nailed it! c: The only thing that really needs a bit work on is the hind legs.
I only felt like drawin two legs lawl
Here's some info frum my brain ouo
-wolves hardly ever look skinny. (unless, of course, they are starving) Their fur coats are extremely thick but do become lighter during hotter seasons.
-their tails look like slightly less-bushy fox tails and are relatively short.
-the fur around and along their necks is very thick and these hairs are usually called "guard hairs."
-like all other canines, wolves can not retract their claws, so they are always showing.
-the shoulders are mostly covered by the guard hairs.
Mmkay, hope it helps!!!
