Reactive Dog? Aggressive Dog? What’s the difference?

Aggressive dog snarlingThe terms, “Reactive” and “Aggressive” are sometimes used interchangeably. Neither word defines the dog, but both words describe behaviour which is very often rooted in fear, and rarely, in dysfunctional social skills.

The only way to fix reactive dog behaviour permanently is to change the emotional response of the dog to the scary thing is by carefully applying a program of progressive counterconditioning and desensitization and having the dog practice self control through specialized interactive games. Changing reactivity to non reactive, calm behaviour requires changing the dog’s emotional response to a perceived threat, whether we are dealing with leash reactivity, resource guarding, or any other situation where the dog becomes aggressive.

Why not just correct the dog with a tug on a training collar, or another physical or verbal correction when he acts aggressively? There are several good reasons not to correct your dog for aggression. The first is that most dogs will figure out that when scary things approach, you become aggressive and confusing. This will stress a dog more, and the dog will often learn to associate the scary thing with stress and getting a physical correction. Then when you aren’t around, the aggressive behaviour tends to increase, and new anxiety related behaviour may show up. Science has shown that dogs who are trained through the use of corrections are more likely to show an increase in aggressive behaviour. Since the early 21st century, at least two published studies have found that dog aggression and anxiety behaviours increased when punitive training methods were used.** Meghan Herron and her colleagues from the School of Veterinary Medicine at the University of Pennsylvania reported in the journal Applied Animal Behavior Science that using punishing techniques when training dogs tends to increase the aggression in the animals, rather than decreasing it.** Not surprisingly, dogs trained using corrections don’t learn as quickly as dogs trained using positive reinforcement with a scientifically designed training protocol. One study even found that most owner directed aggression would cease when the dog owner stopped using physical corrections in training.

The only long term, effective approach to training a reactive dog is always to use a counterconditioning and desensitization protocol.

How long will it take? The time it takes to thoroughly fix any behaviour problem depends on the individual dog, owner compliance to the training program, and how many times the behaviour has repeated itself successfully before the training program began. While improvement is typically seen after the first session, each repetition of the new, calm behaviour will help to make the threat response disappear for good. It can take up to 3 months of practicing controlled repetitions before the new, confident, controlled and relaxed emotions are solid enough to be reliable.
