Aside from avoiding the most common triggers — the presence of food or toys; proximity to the owner; high-arousal situations, such as greetings or preparations to leave; and being together in a confined space, such as a narrow hallway — other treatment recommendations include medications such as fluoxetine (Prozac) and following a “nothing in life is free” program.
Canine behaviorists also sometimes encourage people to consistently favor one dog over the others (e.g., the older or higher-ranking dog) by giving him or her resources and attention first. In her DVD, Dog-Dog Aggression, Patricia McConnell argues against this because, in her experience, it doesn’t work. She suggests other methods of decreasing intra-household aggression, including training dogs to be in close proximity to one another while waiting in turn for a resource. The DVD includes a wonderful example involving McConnell’s own dogs. She asks three Border Collies and a Great Pyrenees to line up, then kneels in front of them holding a pan in which meat has been roasted. By name, she calls one dog forward to lick the pan, then asks that dog to stop licking and back up when it is the next dog’s turn. Her dogs’ body language indicates how much self-control they must exert to succeed in this situation, but succeed they do. The lesson? When dogs learn that they get what they want by politely waiting their turn, they are less likely to bully each other (or you!) as a way to gain resources.
In any event, when intra-household aggression is a serious problem, consult a certified canine behaviorist with a background in this type of situation. In addition, it can be very helpful to learn as much as possible about canine communication to better understand dogs’ interactions. For example, being tuned in to postures and facial expressions that often precede aggression — such as a dog standing very still with his muzzle tightly closed — can allow us to intervene before an attack is launched.

Pleasures of the Pack
Based on my own experience, I hypothesize that relationships between a household’s humans and dogs, as well as relationships among the humans, influence how dogs get along. People who model peaceful, generous and courteous behavior create a household culture that dogs, who are highly attuned to social etiquette, recognize. Puppies growing up in such households are especially likely to adopt that culture.
More often than not, multiple dogs do get along. In addition to the benefits mentioned previously, having several dogs is just plain more fun. One of my favorite activities involves walking my dogs off-leash in wild areas far from roads. Each dog understands that when I say, for example, “Bahati, lead!” I will follow the dog who has been singled out, so long as he or she doesn’t move toward anything dangerous. All my dogs love being the leader, yet will relinquish that role when it’s the next dog’s turn — or mine. It’s fascinating to see where each dog chooses to go; their noses lead us to places I might never find. Also, I can relax because I’m not making all the decisions; it’s fun to be a follower for a change. Finally, letting the dogs be in charge helps balance power in the human-dog relationship. None of my dogs has mutinied, which I think effectively demonstrates that we don’t always have to be “the decider” to have well-behaved dogs.
Based on what scientists know about people, dogs and their mutual histories, these outings in some ways mimic the original relationship between human hunter-gatherers and canines. Hunters traveled with multiple dogs, some of whom tracked and chased game while others protected women and children when they were out foraging. Since dogs can smell and hear better than we can, as well as see better in the dark, it made sense for our ancestors to sometimes defer to canine judgments about where to go (or not go). Most of the time, neither we nor our dogs can live this way, but we get a taste of the wild by going on long outings and allowing our dogs to lead.
