Thanks for all the replies. There were too many for me to list. I think the opinion is that these aren’t Pits, or at least full Pits. There are other dangerous breeds out there that are less well known and just as dangerous while being bigger, but I really think these dogs are hounds, like bear/hog hounds. They are bred to be vicious when hunting but most, MOST, draw the line at attacking people. Most people see hounds as lazy lay on the porch dogs but the big hounds they use to hung hogs are bear are not that way. A lot of them not only hunt but are used as protection dogs, like mine were.
You are right about the weight. True Pits don’t get very big. They are just very strong. These dogs are way too big to be Pits.
Bear or boar hounds that are brindled are Plott Hounds which typically make excellent pets, known for being gentle with kids despite being fearless and doggedly determined in pursuit of their prey.
But, if some deluded ignoramus is crossing them with a breed known for potential aggression toward people they’re going to get a very persistent and fearlessly aggressive dog. Not a good idea, not at all.
