It’s also very important to walk your dogs together, side-by-side. Not only does the exercise help to lower their energy, and hence the impulse to fight, but by moving your dogs forward together it focuses them on a common goal instead of each other.
Whether you’re bringing a new dog into the pack or moving in new humans with their existing pack, the procedure is the same, and you can find it in detail in the article A New Member of the Pack. The short version is that all of the dogs should meet in neutral territory and take a long walk together first, before coming into the home. Then, the humans enter first, followed by the dogs that live there, followed by the new dog.
The first step with the first fight is to break it up quickly and calmly. Cesar explains the steps to breaking up a dog fight, where your instinct is the key. Focus on the dog with the higher level of intensity, use touch to redirect (this forces them to release if they’re biting), and then pull them up (not back). Never yell or shout excitedly when breaking up a dog fight — this will only elevate the aggression. You can use a loud grunt or shout, but always in a calm manner. You’re not breaking up the dogs with your voice; you’re defusing the aggression with your energy.
Dogs in the same pack fight for one reason only: because they do not have a strong pack leader. This is why establishing rules, boundaries, and limitations for the entire pack is important. If all of your dogs are looking to you as a leader, they will not be looking at each other as competition.
By bringing a new dog into another pack’s territory, you are running the risk of the existing pack becoming assertive or aggressive in order to defend what is theirs. Depending on the new dog’s energy, they may become completely submissive and fearful, or they may fight back.
