Dr. Sophia Yin gives some sage advice on breaking up a tussle between dogs. For more from Dr. Yin, find her on Facebook or at!

If you have a dog and he goes to the dog park, lives with doggie housemates, or otherwise socializes with other dogs, chances are that at some point you may need to break up a spat. These may range from low-level altercations with no real contact to a no-bites-spared brawl. So what should you do? First, realize that regardless of the amount of noise, most fights between unfamiliar dogs at the dog park or first fights between housemates are spit and drool matches. When bites are involved during these fights, dogs generally bite and release. So in the majority of cases we do not need to worry about prying the jaws open or getting dogs to actually release.

Instead, our major concern is just getting the dogs apart and to do so without getting bitten. The number one way to avoid being bitten is to avoid trying to grab the head or neck area. Frequently while trying to grab the front end or getting in the between the dogs, the humans accidentally get bitten. Or in the heat of the moment a dog actually turns and redirects aggression to the person pulling them away. The safest method to get the dogs apart is to grab them by the rear end and quickly pull them away.  In other cases, because of your positioning in relation to the dog or because they are moving around too quickly, you may need to shove one away by placing your foot on their rib cage and pushing. This is safer than bending over and trying to push with your hands. It may also allow you to use your hands to grasp the other dog if you don’t have someone else to help.

Other methods for separating dogs include spraying them with water, placing a board or object between them, or banging a noisy object near them. These techniques are all meant to distract them. Other surprisingly benign distractions may work too, says Melissa Morris, a dog trainer who recounts the case of her mom’s dog.  “Her shepherd, Ruby, attacked a visiting yellow lab.  Ruby grabbed the lab's neck and wouldn't let go.  My mom was yelling at Ruby.  My brother-in-law was there and punched Ruby in the head, trying to get her to let go.  All that did is hurt his hand! My mom was holding a newspaper and lightly hit Ruby on the head with it (newspaper was not rolled up).  That distracted Ruby and she let go.”

In another situation Melissa recalls, “When my neighbor's pit bull attacked the chow that was walking by their house and wouldn't let go, they tried yelling, kicking the dog, turning the hose on him, none of that worked.  But when they opened the car door and said, ‘Let's go bye bye, he let go and jumped in the car.’
These two situations highlight that creativity may win over force. Also consider using a spray deterrent such as citronella (Direct Stop or Spray Shield) or pepper spray. They can work in some cases too. Just remember—in all cases avoid actions that will cause the dog to redirect it’s aggression to you or even unintentionally lead to a bite.

What to Do Once the Dogs Are Apart
Once you have the dogs apart you should pay attention—does your dog want to keep fighting or does he immediately calm down or try to get away? The one who wants to continue fighting will require more work to modify the behavior in the future. In either case, you’ll want to understand why a fight occurred instead of just assuming it was a fluke or hoping the same type of situation won’t occur again. A majority of the dog aggression behavior cases involving bites that I treat have a history of getting into low level spats which over time developed into more dangerous fights. Many fights can be prevented simply by noticing when one dog is tense around another and calling the two dogs apart before there’s trouble and then rewarding your dog for good behavior.
