That picture was photoshopped, the wolf came from a photo taken from a Canadian outfitters hunting pictures (seen it many times, unmistakeable), the wolf was photoshopped in, who knows what the guy is holding, probably nothing.
Adult male gray wolves can grow to 130 lbs in a year and a half under the right conditions. They can reach 150 lbs if they have a good pack to help them out. There are a few rare examples that reached 177lbs (one in Alaska and one in Mongolia).
The gray wolf is the largest member of the canine family, although they appear thin, elongated, and under the fur built like a grayhound, they are very heavy, muscular, and far stronger than any dog the same size could ever get.
The average adult male is around 30-32 inches at the shoulder, with a very long body. For comparison my bigger dog is 27 or more inches at the shoulder, and 80 lbs, also Im 6ft tall.
Its a shame to kill the alpha male or female, they mate for life, and teach their pack to fear humans, avoid livestock, and stay inside their territory.
The single roaming young inexperienced skinny little single male or female without a pack are the wolves in 99% of all cases which cause problems actually involving wolves.
