Oh yeah. I know A few REAL GOOD curs that open quite a bit. They must be moving track faster than the speed of sound though becuase they catch a crap ton of hogs and every body knows open dogs can't catch hogs.

I have a male ybmc that is open about every 20-30 seconds he will bark bout 3-4 times terry has hunted behind him and I'm sure he would vouche for me when I say I don't think it makes a difference cause we have caught just as many hogs behind my open dog as we have behind our silent dogs
