Kevin your right about all dogs were crossbred at one time or another...If I were to hunt catahoulas or bmc the first thing I would do is put some walker or plott in there...
most mt curs are too small for my liking so a little walker or plott will fix that...but I believe that once we develop a line of dogs we then must do our best to line breed or inbreed to reproduce what is working...the linebreeding will eventually clean up the gene pool so that we are producing a higher than average percentage of what we want in a hog dog...I tend to look at hog dogs from the breeding side of it...

my goal is always the same...to have a hog dog that is worthy of breeding so that it can help me to the next level...whether I am breeding 3 litters a year or 1 litter every 3 years...
