I've only been around one, a 4yo male I was given that was completely unsocialized, had never seen a hog... best free dog I ever got
In my opinion... if you aren't truly dog savvy, you don't need to be messing with a big dog like this... smaller dogs you can manhandle and get away with it... this dog I've got could reeeeaaally hurt you if he wanted to... took me a few wks of intense handling to get him to come around...
Dog aggressive? As much as any other dog I've seen, varies from animal to animal... Proper training helps control this...
Catch style? Some do, some don't... one way to find out... just make sure you got some handle on him before turnin' him on... Mine catches by the top of the skull every time, as good as it gets.
Hunt? If I let mine, I know he would... but I don't want my catch dogs to hunt... if they miss a catch, I want to be able to get my hands back on them so they don't roll out and end up catchin' a mile away... get dogs hurt bad like that... He's got a hell of a good nose... but there again... you better have a hell of a handle and make damn sure he's trash broke... no fun tryin' to pull a dog that size off a pissed off bull...
Again, this is just my opinion on a whole breed based on the ONE dog I have to go by... so take this accordingly...
He is, to me, a giant cur dog, a "rough" cur dog obviously... but that's the type of curdogs I hunt so I see the similarity... way more similar than say a pit or bulldog... Just as my curdogs will catch a hog they know they can handle by themselves, so does he... Just so happens that he weighs better than a hundred pounds though... so what "he" considers a reasonable hog to try verses my cur dogs is a bit different!
He is WAY more intelligent than a bulldog, he TURNS OFF when I tell him to... VERY nice with a dog that big...
Just be very, very, careful... you dealin' with a lot of horsepower...
