more slender and light wieght pit

me to. i think i got a plan for a cross that hasn't been tried yet might even make a new breed of dog like a pittbull but more athletic and slimmer. I think their size is over kill for hogs. they maybe were bred for bigger animals. I have a cur catahoula cross smaller dog for the breed That will drag the hog toward me. She grabs pigs that i cant believe she feels confident enough to grab without another dog that catches hard. What is more amazing is that she can drag them. they may be rough at first but she stays latched and pretty soon they wear down a little and she will start pulling em toward me. I think i want one that will catch hard but i don't think they need any more power than the average dog I would rather replace that extra muscle with agility I just want that reliable bite of the pit.
