Aggression Is Not a Moral Failure
I wish more people understood this: punishing a dog for aggression doesn't solve the problem; what it often does is suppress the warning signs while making the underlying fear, anxiety, or frustration worse.
Growling, lunging, snapping, and biting are distance-increasing behaviors. They occur when a dog perceives a threat and is trying to make the threat go away.
The dog isn't being “mean,” and the aggression isn't necessarily about disliking the person at whom the aggression is directed. In fact, fear is the most common cause of aggressive behavior. A dog who's frightened, overwhelmed, conflicted, or trying to create distance isn't necessarily intent on doing harm.
If a fearful dog is punished for growling, he will learn to bite without warning. While we may have successfully eliminated growling, we will have done nothing to address the underlying emotion—and are likely to have only made it worse. In effect, we will have removed the warning signs without removing the danger.
Not using punishment to modify aggression isn't some trendy, “soft,” or permissive approach to dog training. It's behavior science.
It just isn't as simple as correcting misbehavior. For punishment to be effective, the delivery must be perfect— including factors such as timing, intensity, and consistency. Humans are generally incapable of applying punishment with the precision and consistency required for it to be effective without causing unintended consequences.
Too often, the use of punishment gives the illusion of success due to the immediate suppression of behavior, and it continues because the individual doing the punishing is reinforced.
Consequently, the underlying reason for the behavior remains unaddressed, the emotional state of the dog worsens, and the problems associated with the use of punishment pile up, problems such as fear of the punisher, increased anxiety, inhibited learning, the need to use more and greater degrees of punishment.
Shaming a dog doesn't teach a moral lesson, either. Rubbing a puppy's nose in its urine or f***s, or hanging a dead chicken around the neck of a dog that killed a chicken doesn't teach the dog a moral lesson. It creates confusion, fear, and distress.
A 2009 University of Pennsylvania study of 140 dogs with behavior problems found that confrontational methods didn't simply “correct” behavior—they frequently elicited aggression. Forty-three percent of the dogs responded aggressively when hit or kicked, 41% when their owner growled at them, 39% when an item was forcibly removed from their mouth, 31% after an “alpha roll,” and 30% when stared down. The researchers concluded that these techniques can provoke fearful or defensive aggression and may increase the risk of owner-directed aggression.
So when a dog growls, lunges, or bites, the answer isn't to respond with aggression to show the dog who's boss or to force the behavior to stop.
Ask why the dog feels threatened. Keep everyone safe, and address the underlying emotion.
Do this under the guidance of a qualified professional who uses humane, evidence-based best practices in behavior modification—practices such as systematic desensitization, counterconditioning, antecedant arrangement, differential reinforcement of incompatible alternative behaviors, classical and operant conditioning, and more.
If anyone tells you they can fix aggression quickly, this is a red flag, and that trainer or behavior consultant should be avoided. Mental health conditions in people are not fixed overnight, and they aren't in dogs either. Just like you wouldn't punish a human for an emotional illness, it's no more appropriate to punish a dog.
