Breaking up a dog fight can prove to be unsafe for most people, even wearing your best brooks running shoes you will probably not be able to outrun an angry dog. Once two dogs are in fighting mode, their main goal is survival. An instinctive way to protective themselves is by using a series of quick bites and movements. You should never be caught between the two dogs, but if you absolutely must break up a fight - get another person. The two man approach is safer then handling this scenario by yourself.
Never reach out to grab the dogs in attempt to close their mouths. This is by far the worst method you could take for stopping a dog fight. Usually when a person does this, the fight will be directed towards them instead. They could easily chomp down on your fingers with their teeth.
If there is another person to help out, you both can do the “wheelbarrow trick”. Firmly grab your dog by its hind quarters, quickly lifting it up off the ground. While you are doing this, you should walk backwards while side stepping so that the dog can’t reach back as easily to bite you. Once you both have done this together, walk the dogs to their separate kennels or take the other dog home if it is a neighbour’s dog.
You can also use a fire extinguisher to spray them. Most dogs will jump at this and others will not, so it may or may not work. You can also spray them with a water hose to stop the two from inflicting any more injuries. One more item to use could be a broom stick. Simply put it between the two, pushing one dog away from the other with it. Do the same to the other dog until you can leash him/her and bring your dog inside.
For any aggressive dog fight, a noise-making device is a great asset to have. Remember that most dogs have extra sensitive hearing, so an air horn will mostly likely startle them. If you must, you can blow the air horn twice to get them away. Also, silent devices made to stop dog barking can help a situation like this.
