Looks to me like the camera was next to the ground when taking the shot. Look at the dog's hind legs and the angle. I've taken some pics of deer and such in that manner and the perspective makes the deer look huge compared to me though I was right up next to the animal. Camera angles do weird things.

The wolf I killed in 09 is sitting at #31 SCI and looks smaller than the one posted here. He was a guesstimated 120-140 pounds. The rumors of 200 lb dogs running around in MT make me laugh.

Regardless the hunter above has succeeded with the ultimate trophy and envy of MT hunters. Good for him.
