The utilitarian breed was used for everything from serving as watchdogs, to gathering scattered stock, to rabbit hunting, to treeing various small game intended for the pot. The breed designation came later. At some point, mountain feists were separated from their larger cousins, mountain curs, and they became associated mostly with squirrel hunting. A Heinz 57 of a dog in looks, the mountain feist distinguishes itself more by its ability to see, smell and hear squirrels, and tree them in workmanlike fashion, than any particular physical attribute. Size-wise, they’re runts.
