The best known guard dog in South Africa is called a BoerBoel. The are great guard dogs, and look as scary as they are. You are asking the wrong question. A dog isn't "ferocious" by nature, it depends on how the dog is raised. Yes some breeds make better guard dogs than others, but even a Chihuahua can be raised as a guard dog. I have Yorkshire Terriers, and all but one of them couldn't hurt a fly. My one female Yorkie, Misty, is one of the most ferocious dogs you could meet, and she is 6lbs. You should not be looking for the most ferocious breed but instead be looking for all the qualities your friend wants in a dog that has guard dog potential. Then all you have to do is raise him or her the right way.
