Don't know about your "wolves" but OURS stink to high heaven when skinning them, even if you don't puncture the gut - which adds another level to the stink.
Had to do 3 wolves in camp one fall - nasty stinking beasts, especially when you have to turn the ears, turn the toes and skin out the heads/teeth, etc. YUK!
Once turned into a rug, there's be no stink, of course.
