Isolating several pets in a small area can also invite disaster. It is advisable to separate them with baby gates or by crating. If you have not seen signs of aggression among your pets and there has always been peaceful coexistence, chances are you will not have a problem, but observation is the best defense against fighting among greyhounds. Even greyhounds who have never shown any tendency for discord among themselves can fight. A dogfight is a most unsettling sight, not to mention the sound.
Immediate intervention is the key to preventing or limiting injuries.
Stomping your feet and making any abrupt, loud noises will help distract the dogs from one another. If you are outdoors, spray them with water. Trying to physically separate fighting dogs can be extremely dangerous. If you cannot resist the urge to intervene physically, grab for a collar from behind the dogs so that once separated, you will have control of the dog. Fighting dogs can direct their fury on anyone or anything, so be prepared to keep a tight grip on the collar until the frenzy subsides.
