Dogos had bull terrier injected into the mix a couple times, but they are a hodgepodge of breeds to get the result. The base was the Cordoba fighting dog, which is know an extinct breed.
I like hog doggers that respect property boundaries (I realize this is tough with dogs). However, hog doggers that intentionally trespass and don't care make my life miserable. I oversee a fairly large trapping operation, with the goal of taking out entire sounders at one time. On numerous occasions, the night we plan to drop the doors, we suddenly have pits/hounds/cur dogs pop up on camera. My trappers now have instructions to drop the doors on any dogs in the trap and call law enforcement. Those dogs set us back an average of 10 nights. They may get a few, but for the time being it is more of a forced dispersal......that being said, I do like dogs when you have trapped out an area and you have some stragglers that are trap shy.
Several hog doggers I know have gone out of their way to distance themselves from being known as hog doggers (my trappers won a lot of tournaments, and my uncle has made the cover of the regional hog dogging magazine several times). Check out any of the FB hog dogger pages and you will figure out why (the moderators usually try to clean them up, but catch them about 3 PM and it looks like Meth -R-Us and assorted baiting dogs).
