Ha! That's so funny. I had a cat from the age of 5, until I was 22, who was cornered by two seperate dogs and I witnessed both. She scratched the beagle (who bit me in the ass when I was younger) in the face, then ran off.
Second time, it was my friend's dog and we were both outside when we noticed that his GERMAN SHEPHERD had my cat (aptly named 'Troubles' because when she was born she beat up all the other cats in the litter) cornered against my pool (which was rectangle with thousands of corners from the railing). "Troubles" attacked it and then ran into the garage through a crack in the back door. So I went inside, quickly, then came back out and my friend was holding his hand in front of him, while he was standing next to his dog (named 'Liebshen', German for his breed, maybe). The first thing he said was, "Chris, my dog's bleeding."
