I have relatively loose baying, cowdog style curs, they get beat sometimes like any other dog, but them jokers can fly, they get ahead and they are persuasive. The older/ better ones combine speed and experience to bay hogs and they don't have to be cob rough to get the job done.
I don't wanna argue with anybody but ill give an anecdote;
ive got an old bitch who got crippled a couple years ago putting a boar back into a sounder and early this year I pulled her out of retirement purely for her own enjoyment and after about the 7th or 8th hog of the night, she lined out another big sow and was busting butt trying to stop her in the thicket when the sow couldn't stand the heat and tried to cut an open field to gain some distance. less than 200 yards into the field she was bayed solid, when we got to her we realized the bitch had been cut thru the tendon on her GOOD back leg! She had run down that sow carrying herself heavy on the front end, using her crippled leg to push off of!
sounds like pure HEART to me.
Lots of things I have seen, but that one example reinforces to me that a dog don't have to be loose or rough, hound or cur, they just have to "be able", and "want to" more than the hog.
