I dont hunt because I live in the big city nowadays. When I did I was focussed on feral animals that cause so much damage here,pigs,foxes,cats,rabbits.
The guys that do hunt pigs here are a mixed bunch.There are guys with guns & dogs & then a bunch of adrenalin freaks with dogs & knives.
. Young fit men with no fear.( or sense) that run after their dogs.
You need to live somewhere out of the big city to have the dogs.They are bred to be suitable for the country & suitable to the team they are in.
I see people that have a mixed team, finders & holders.So you might have something leggy like an Irish wolf hound cross with a bull arab to chase then a couple of big pit bull X mastiff x bull arab to do the heavy work when they catch up. There are specialist makers of neck & chest protectors for dogs ,a lot made out of the stuff they make fire hose out of or canvas. Radio collars popular as well.
In open plains country you want dogs that will jump of the back of your truck & chase. In heavy tropical country,sugar cane ,swamps you want bigger heavier dogs that crash through.
When I am out in the country for work you see utes(pick ups) with big dogs in cages. It can be a bit of an issue between land owners & hunters.
