He has Houses Lipper show up 5 times in his pedigree and he would catch a hog less than 100 lbs or so by himself and catch any hog with a cur dog.
Lipper was suppose to be an alligator. He was known to throw lots of good dogs but also sired more dogs than any treeing walker in history.
Never thought about it but guess that aggression would make for a good hog dog.
