I was frozen in place, unable to move. Perhaps it's because I didn't want to endanger my dog, or perhaps I just panicked. I couldn't see what the bigger dog was doing, but soon the smaller dog started yelping horribly and the bigger dog walked away.

I still couldn't move. Then, after a few seconds of the yelping, the bigger dog came back, made some more growling jabs with its muzzle down below where I could see, and the other dog was silent. The bigger dog walked away then, and didn't come back.

A man came out of the house in front of which the fight had taken place. He had a horrified expression on his face as he knelt down to the smaller dog. I don't know if it was his dog or not. He then looked up at me, a hundred feet away and still frozen in place, with an expression I could only read as "why didn't you do anything?"

I looked down and continued on my walk. I never saw the smaller dog, but I could imagine it struggling in a pool of blood.
