I've got a 10 mo. old Rhodesian Ridgeback puppy, and a 14 yr. old as well. The older one has arthritis so she ain't movin much, but was reported to have been seen killing a pig, and has chased pigs through our yard. Plenty of people here in Hawaii use Ridgebacks for hunting pigs. My 10 mo. "Kaya" has shown interest in hogs, as well as wild chickens. She will bay my cats up into trees and chase them through the yard. She won't grab anything with her mouth except chickens. I've taken her hunting before with my friends Pit and Brittany/Pit mix, as well as some little puppies that couldn't do much. The two pits ended up grabbing a small sow and my dog was baying it. I've heard of them being used to point birds. My dog already has the instinct to point when it's smelling things. They'd be a great dog to flush rabbits with, it'd probably catch them though.
