i don't know anything about them , just know i have some way back in my Dogs.. now i can say this , they have no dog are human aggression !! but i do think you have to start them young , because afer one year I find they Curr Out to Everthing if you don't let them hit a hog young.. all in all , IMO i think it would make you a damn find CD ... they my run hot and be a little short winded , but smart and intense at the same time !
