A friend had a really big male cat named Fang who was very territorial. He would attack any animal, including dogs who came into their lawn. There was a neighborhood German Sheppard who was attacked by Fang and needed nearly 100 stitches to close the wounds inflicted by the cat. The cat was put down after attacking and seriously wounding a child.

I had a cat that would chase dogs. Otherwise he was very tame.
