Hi Stabs
There are plenty of dogs over here that can do that type of work my tean consist of 2 staghounds and a ridgeback. we catch plenty of hares as well as our share of pigs. Its pretty important to consider the country you are expecting to hunt, open or lightly wooded flat country suits my dogs the best though we do hunt in country you described as well. mountian pigs tend to be harder to find then the pigs out west and you need a dog with a good nose and high work rate to cover all those creeks and gullies you talk of, My nabour has a bully/boxer cross boarder collie that adds another
