Inter-dog aggression is fighting and aggressive behaviour directed from one dog to another dog. The most common cause of inter-dog aggression is food related, but it can be triggered by household changes, and can happen when dogs are fearful or over-excited. It is important to learn to understand dog body language to help predict fights.

When these fights occur, always remember, SAFETY FIRST. Never come between two dogs that are fighting as they can injure people very badly without meaning to. Use loud noises, water (like the spray from a hose) or throw a blanket over them and use a broom to separate them. Once they have separated, take the dogs away from each other to prevent another fight breaking out.
