Anything can happen in a split second, especially when it comes to catching hogs with dogs. Nearly got ate up in a pen the other day training a bulldog on a smaller hog and she decided to regrip and he got away and nearly got me. I remedied that by putting a big rank boar in there with her next and after a little bit of a whoopin by that hog we couldnt break her off that hogs ear. Had to go ahead and mark the hog and let her have the ear.
ABs are notorious for being mouthy and I have broke them of that the same way and in PP work I use a garage spring or bungy rope and get just in reach where they have to stretch it out and bite and hold. If they regrip they loose the bite all together and I dont give them another one for a day or two. If a dog continues to be mouthy its your call if you want to take the chance, but you will not hunt it with me.
