DD - google pigdogs and you will see what I mean, they are trained to crawl through the bush and JUMP on the boars. They usually wear armor to do so - feral pigs have massive tusks. It's a bloodsport. Literally (ick).

In order to be a good pigdog, they must be bred big and sometimes bulky, so we are talking mastiff X's and staghounds etc.
My brother had a litter of pups stolen once and he was shattered as they were the culmination of years of breeding. He went to the neighbours and let them know the dogs were piggers, not suitable to be sold and not much use to anyone else. They reappeared magically in the backyard 2 days later......
