they would have to go as a pair. 2 males (litter mates). they killed anything with a heart beat that wasn't an adult. We never tested them around kids. They ate cats (fur and all on 4 occations I know of), ran down a 400lbs calf and had it down. One was on its head the other pulling its back leg when I got them off. I found remains of sparrows that they caught. I guess the didn't like feathers. They would have loved to fight any dog that crossed their path (they were leash broke and obeyed on a walk but it was there). It was nice to be confident that if an intruder broke in the house they would literally eat them. If heard them attacking somebody in the night. I would probably just go back to bed and call the cops in the morning after they got their fill.
One bit me once,when I fell asleep petting the other. I honestly believe he was just surprise attack the other and my hand just happened to be on his neck.
I don't know anybody that would want a pair of dogs that eat 50lbs of dog food ever 6 days, that can't be around kids or other animals, and have to have a 6ft fense that it electicaly charge.
One was nice and wasn't "that" aggressive. He joined in the fun when the other lead. He was so co-dependant on the mean one, he wouldn't been able to function. He would tear the house apart if walked them seperately. They literally never spent more than 30 minutes apart in their lives.
