Many people that don’t think hogs are hyper intelligent are basing there opinions on encounters with young hogs of up to 2 years old. My favorite North American big game species is a 4+ year old hog. I consider them the most intelligent animal in the world. Furthermore, I don’t think any animal is even close as a second place. There are old hogs that frequent many heavily hunted areas that will never fall to a hunter. On a scale of intelligent behavior combined with vulnerability to hunting, a 5 year old hog is a 10. A mature whitetail buck is a 5- at best.
