Hey there,
I just got a mountain cur pup, and they are strong tree dogs and strong at baying. I know of some people whose curs regulary tree bears, and another guy here in OK has his kemmer curs treeing bobcats. I'm sure there are guys that get their curs on big cats. There are several different strains, too. original mountain cur, blackmouth cur, kemmer cur, stephens cur, many more. Check out sqdog.com and take a look at the "forums" section to learn about curs. Then maybe you can see what you like and dislike. Hounds are probably great, too, but don't X out the cur, yet, as they are truly an american breed with all kinds of qualities. FYI, "OLD YELLER" was the story of a cur!!
