What do you think is needed to manage a dog aggressive dog?
1. Keep yourself and other animals safe at all times. Prevent, manage, train, modify behavior through desensitization/counterconditioning.
2. Don't be ashamed to put your dog in a muzzle if the dog is truly aggressive, and not just reactive, or you aren't sure. What other people think is not important because it's your dog that could die if there's an incident. Preventing a "bite history" is very important!
3. Be sure to rule out any physical cause for your dog's aggression before you establish a training or behavior modification protocol. Medications can help some dogs, either short term or long term, so don't necessarily avoid them in favor of other modalities. Positive and holistic people tend to view meds with suspicion, which is good, but if your dog could benefit (again, think safety) don't reject them just on principle - see what really works. Case in point: Mr. X, small terrier mix shelter rescue, couldn't be touched by anyone but owner, terrified of grooming, handling, etc. After going on Clomicalm, Mr. X walks into the grooming salon, tail wagging, and everyone can handle, bathe, and dry him with no problem! There are almost no "magic bullets", but occasionally we do see remarkable improvement:-)
4. Do not try to use aggression or pain-inducing equipment to treat aggression. You can make things much, much worse.
5. Realize that aggression is normal, a coping mechanism for ALL dogs, it's just that most dogs have a higher threshold for being triggered than your dog does. Work below threshold all the time. The more the dog realizes he was ok, and didn't have to use aggression, the more he will treat similar experiences without using aggression. Practice makes perfect. Work toward practicing calm, and rewarding bravery, NOT on waiting for the dog to be aggressive so you can punish it.
6. The best way to prevent aggression is to socialize puppies EARLY!!!!! Your dog may not have had the valuable lessons this provides between ages 8-12 weeks. (The American Veterinary Behavior Society believes that you should not wait until your pup has all its shots! The reason? By then, the socialization period is virtually over. Is it risky? Sure. But, behavior problems are MORE risky to dogs' lives overall.) When choosing your next dog, choose a dog that is SOCIAL (don't take one that is a liability just because you feel bad - taking that one might mean a really good dog has to die), or get a pup from a reputable breeder (they start the socialization process early by taking puppy to different places, putting them on different substrates, making noises acceptable, etc.) and continue the socialization process as soon as you get the puppy home. (Avoid places where dogs urinate and defecate, but take him everywhere, enroll in puppy class (if no one takes pups that young, show them the AVSAB position paper on puppy socialization, and educate them!) or join or form a puppy play group (meetup.com).
7. Don't watch TV, read books, or visit web sites, and expect to know what to do. Get a professional behaviorist or trainer who is experienced with aggression, to help you. Your dog isn't the dog on TV and the solution may not be right for your dog (and that goes for EITHER Millan or Stillwell!) Many other problems can be solved hit or miss, but aggression is one that you don't want to get out of hand. IAABC or the Animal Behavior Society are good sites with listings of pros. You can also get referrals from the nearest vet school.
8. Never excuse aggression, just analyze it. Why is the dog using aggression (what's the trigger?) Is the dog being reinforced for using aggression, and how is that happening? (If we recognize the trigger, and the reinforcement, we can avoid triggers and remove reinforcement. Dogs do what the receive reinforcement for, whether it's an environmental reinforcement, or it comes from us.)
9. Learn all you can. There are some great behaviorists who have DVD's on various forms of aggression. Even if you do use a behaviorist, it helps to learn more. Tawzer Dog Videos is a good source.
10. Love your dog - just manage your dog, too.
