The reason why hounds were not trained to fight other breeds was because they were supposed to work together. By each one doing their assigned task Hades was kept safe from wandering intruders and no one escaped. Mal only knew as much as he did about the other hounds because he'd been around so long. Time was one of the best teachers and Mal had plenty of it under his proverbial belt.
As soon as Ziv released his tail, he flipped it out of the way though it screamed in pain. Loosening his jaws a bit, he clamped down on another part of her leg, tearing through to bone once more. Of course, that meant he was not quite as focused elsewhere. He howled when he felt his sac being ripped, jumping off her throat and leaving her bloodied on the ground. A few feet away behind her, he closed his eyes for a moment from the pain, opening them quickly to keep track of Ziv.
She was smart, and she fought dirty. Just like a bitch. Apparently it'd been too long since he'd mounted one that he'd forgotten just how brutal they could be. Flames shot out from his paws once more as he pushed his pain to the side. He'd deal with it later. Mal charged Ziv, aiming his jaws for the back of her throat. He was going to scruff her and slash her wings to ground her.
