Ideal traits of big game hound

The good big game hounds are the ones who come out of proven parents. I've got a 3/4 walker 1/4 bluetick dog that is hog crazy. His dad was a coon dog reject that liked to strike hogs and his momma is as gritty as any cur dog I've hunted with. I don't know the bloodlines and I really don't care, all I know is that he hunts for hogs. Now I hunt him with curs and that's it. Oddly, he hunts closer than my catahoula, but I've never run him with long range, open mouth hounds in an effort to avoid those traits. As far as grit, sometimes he'll be in there on the catch no matter what size the hog and some days he'll decide just to bay. The good thing about him is that he'll stay with it all day and I can HEAR him to locate the bay. He's a loose bay dog when he's alone and if your hogs are dog savvy, that's a bad thing. Not sure if they're all like that or not. If you're looking for advice, I'd suggest hunting with their parents first and see what your getting. In my opinion, a good silent hound is worth its weight in gold when it come to FINDING hogs. Some guys hate 'em though.
