Hi - The dog is a ridgeback cross staffordshire terrier!
I don't currently hunt with dogs, but I used to hunt bushpig with a pack of hounds (beagle/foxhound/bluetick).

Currently it is still legal, and there are specialised packs which are game proofed, and so can hunt bushpig and probably warthog in game rich areas with minimal disturbance to other game!

Have to say that bushpig hunting with a dog pack is very exciting, and extremely good excercise!
