Aware? If I'd ever seen one I would have recognized it. I live in sled dog country and have never seen a pit bull in harness for anything serious. I was a first responder and never saw a pit bull mountain rescue or tracker. I've hunted upland game for many years, watched numerous field trials and never saw a pit bull participate.
Lots of folks don’t use their dogs for the functions of which they are capable.
For example how many folks have Labs for the purpose of retrieving.
Many folks have their dogs primarily for companionship
Just because folks don’t use their dogs for these functions doesn’t mean they are incapable of being so used.
Now I wouldn’t claim that “pitbull” type dogs excel at sledding.
They can do it and certainly enjoy it up to a certain point
but realistically they aren’t physically designed for the extreme cold in the way of husky types.
My next door neighbor has a husky type who appears to love laying outside in the snow, the colder it is the more he seems to enjoy it.
My dog could not do that, he is short-haired and would be whining to come indoors before long.
In a similar fashion I would guess that while they may be capable of it,
you wouldn’t find too many husky types hunting wild hogs in the southern US.
As far as rescue work, tracking or hunting
with recognition that even among the ‘usual’ participants there are degrees of aptitude,
there is no reason that, with training, “pitbull” types can not excel in those functions.
They do after all have a terrier component to them that lends itself to tracking and hunting.
