Important: The following is meant to provide a general overview of dog-dog aggression. If you're dealing with an aggressive dog, seek help from a reputable behaviorist.
Dog-dog aggression is a very serious matter. Until your dog's successfully treated, keep him a safe distance from all other dogs ("safe distance" meaning the minimum amount of space he needs to remain calm and unstressed).
Even if physical contact is never made, managing a dog who's pulling and lunging on-leash is very difficult--not to mention stressful for all parties--and attempting to defuse an attack in progress is downright dangerous.
If you see these behaviors, calmly remove your dog or redirect his attention to something else.
Nature and nurture each play a role in shaping your pup's personality. True, certain types of dogs have been bred specifically to be aggressive, but with the right training and socialization, environmental factors can and often do triumph over genetics. Similarly, breeds known to be gentle and easygoing can become highly aggressive if mistreated.
If you've brought home a puppy, you're in a good spot: his behavior is yours to shape. If you have an older dog and you suspect he may be dog-aggressive, training--or rather, retraining--will be much trickier. In such cases, consulting a professional is always the best path.
Most behaviorists use desensitization to treat dog-dog aggression. Using plenty of positive reinforcement, you'll gradually decrease the physical distance between your dog and other dogs without raising his anxiety level. This takes a great deal of time and patience--often several months to a year--but ultimately your dog will associate the approach of other canines with good things (praise, treats, attention). Get guidance from a behaviorist before beginning desensitization.
In the meantime, don't increase your dog's stress by physically punishing or yelling at him, and forget prong or choke collars. Added pain and stress will only escalate your dog's anxiety and increase the aggression. The last thing you want to teach him is that the presence of other dogs mean bad things happen.
There's no surefire way to prevent aggression, but there are basic steps you can take to greatly decrease the chances your dog will develop a problem:
Bottom line: Dog-dog aggression is treatable but nearly always requires the help of a trained professional (and lifelong vigilance). Doing everything you can to prevent it in the first place is a much better option.
