Carlos & I discuss the techniques WE use to break up a dog fight. 

DISCLAIMER: Dog fights are not all the same. Dogs fighting can be fighting for different reasons. Dogs fighting are usually not evenly matched. Breaking up dog fights is a skill that can be learned but it is risky and it is definitely not for most people to attempt. It requires confidence, timing, quickness, agility, and strength. Breaking up a dog fight can be very dangerous both to the people trying to intervene as well as the dogs in the fight. Do not try these techniques on your own at home without consulting a professional.

The video we mention is on YouTube and entitled "How to handle a Dog fight - Cesar Millan" posted by Peter F. Zorko. There's a very good comment left by "stuart" from 4 years ago that appears at the top of the list of comments below the video.
