Mr. Mason raises some fine Catahoulas and you will not meet a more stand up guy. Country to the core, getting on up there in age, but still trains them, raises them, and hunts them. I cant count how many other people use him to train their hog dogs (which is what I am assuming you are looking at Catahoulas for).
