LOL, please share the link that has the information on the wolf's growth status. I have read a bunch of the accounts, watched vids, and seen the pictures and nothing has mentioned this revelation and the images are not indicative of any particular growth stage. In fact, age, size, and weight information seems missing from all of them.
Watch the vid. in the link I provided and you will see how big the wolf is. You will also see that the size of the wolf, whether it's 1/2, 3/4 or full grown, it's exact weight,sex and age is irrelevant.
It was big enough to severely hurt or possibly kill this 56 yr old frail woman.
Again, point is, this frail(but feisty) woman acted in a dangerous, time essential situation.
