We have a chap here in Australia that kept Boargreyhound and an from what he has said they are very simular to the stag or kangaroo dog both these breed were exported to Africa and india during colonial times the african dogs have been infused with ridgeback and boarbul for thicker skin and stronger bone. So I have been told. he used his dogs on all manner of antilope, jackal, brown hyeana and warthog.
