This was a fine video, but I disagree with one. The pit bull is not really a breed that has undergone much transformation. I would not say it is the most untouched breed, but I don't reckon it could be put in a list for one of the most transformed dog breeds in history. The only thing that really changed about the bulldog (bulldog is what some folks call pit bulls and used to call pit bulls in the past due to their use as butcher's dogs and bull-baiting dogs) is its reputation. One thing I would say is that bulldogs have always had different sizes and builds to them even during the says of bull baiting. That is because pit bulls have always been used for different work. In the past, they were bull baiting, being matches against other bulldogs, and also hog hunting. Some were even ratting. Another thing to keep in mind is that there are different breeds that have come from the pit bull such as the American staff and the American bully that are more muscular and have wider heads that people also call pit bulls. That confuses folks into thinking they are all the same breed. One thing the video said is that pit bulls used to look lighter and slender in its build, but there are pit bulls that still look like that today. One need only take a gander at the game-bred lines. The dogs still have the lean, medium-sized build some folks that do not know better would even refer to as skinny.
