Understanding Dog Desensitization Process

How do you desensitize a dog and how does systematic desensitization work on changing behavior in your canine companion? If you are here, most likely you own a dog that has developed a strong emotional response to certain stimuli in his environment. Anxiety, fear, aggression or excitement, may be the underlying emotions at play, while barking, lunging, pacing, snarling or shaking are the outward manifestations of such emotions. Whether your dog responds negatively to people at the door, the sight of other dogs, or thunder, the process of desensitization may be effective if you introduce it correctly and know how to increase its benefits.

So what exactly is desensitization? Desensitization is a form of behavioral therapy used in the field of human psychology, but it is effective in animals as well. Its primary function is to present the frightened stimuli in such a way that it appears less intimidating.

For instance, if you suffer from arachnophobia (fear of spiders), most likely a therapist will have you take a look at pictures of spiders, he will never start out by placing you in a bathtub full of them! This gradual approach, where the frightening stimulus is presented in a less frightening way is what desensitization is all about.

The process of desensitizing a dog is therefore done while keeping the dog under threshold so the dog can cognitively function and the lines for learning are open. To learn more about threshold levels please read " Understanding threshold levels in dogs". What this means, is that your dog is exposed to the smallest amount of the frightening stimulus, just enough to detect and create awareness of it but without making him freak out. In other words, if you see a picture of a spider, most likely your heart will not race and you will be less likely to scream than when you have one crawling on your arm!

Sensitization and Desensitization in Dogs

How and why is a dog likely to react to certain stimuli he or she perceives as frightening/exciting/arousing? Let's imagine for instance, that your dog is a puppy. The first spring storm comes through and he seems pretty much unfazed by the thunder. Then another storm rolls in a week later and a strong rumble of thunder startles him. About 15 minutes later another loud rumble comes and your dog runs under the bed. Because running under the bed makes your dog feel safe, this behavior will self-reinforce.

In other words, he will continue seeking the bed now every time he hears thunder. Because the continuous rehearsal of this behavior along with nothing happening to your dog (after all, when he hides he makes it through the storm with no harm) this behavior puts roots and soon you have a pretty reliable behavioral problem. Suddenly, you have a dog scared of thunder, actually, not only is he scared of thunder, he has learned to even start getting frightened at the very first signs of a storm coming. Yes, dogs are very good in sensing drops in barometric pressure, vibrations, and subtle changes in the static electric field preceding a storm, according to Alex Liebar. And because dogs live through associations, they soon learn to pair these changes with the upcoming storm.

So what happened? If the dog didn't care much about the thunder initially, but got scared at a later time due to the stimuli being more intense, most likely the dog became sensitized to it. Sensitization is the opposite of de-sensitization.

While a dog can become sensitized to a stimuli, it is also true that a dog can become desensitized to a stimuli, so the process is reversed. In other words, a stimuli that becomes more intense, more frightening, more intimidating is more likely to lead to sensitization, whereas, a stimuli that becomes less intense, less frightening and less intimidating is more likely to lead to desensitization and habituation.

For this reason, should you decide to desensitize your dog to a stimuli, you must make sure you have a pretty good program with good sub-threshold exposure, 'cause sloppy desensitization will lead to sensitization. Sloppy in this case means sudden exposure to intense stimuli rather than gradual, subtle stimuli. Basically you are "flooding the dog"


What if There Is No Threshold Level?

In some unusual circumstances, you may notice that you cannot find a a way to work your dog under threshold, either because your dog's reactivity levels are too high or because the environment you are working at allows no distance from the trigger. What to do in such cases?

In such a case, you have some options:

  • Walk the dog for an hour prior to the desensitization session. When tired, some dogs are less likely to be reactive.
  • Find a calming aid to take the "edge off" so your dog will be less aroused. In some cases, Thundershirt, an Anxiety Wrap or Storm Defender may be helpful.
  • For severe cases, ask your veterinarian for advice. Your dog may need drugs and a behavior modification program with a behavior professional.
  • Find the highest value treats and use counter-conditioning along with desensitization (highly recommended)


So How Would You Desensitize a Dog?

Curious to see a step by step process on how to desensitize a dog? Let's take a peak. For instance, let's say your dog is reactive towards door knocking. We saw a little part of this previously, but now let's go more in depth. Here is a gradual step by step guide:

  1. Start knocking on a table far away from the door very lightly, if your dog barks, you need to knock more lightly, almost imperceptibly.
  2. If your dog does not react, then you can proceed and make the knocking louder. If your dog barks, you need to knock more lightly.
  3. Start knocking in areas closer to the door. At increasingly louder levels as before. As always, if your dog reacts, you are going to fast for his comfort, so start at a lower level of intensity.
  4. Then start knocking the door from inside. Start lightly, and then gradually knock louder.
  5. Knock from behind the door; start lightly and then gradually knock louder.

Because all these knocks were not accompanied by a guest entering the home, they are gradually becoming less relevant and more meaningless. In order for desensitization to have an effect in this case, the number of knocks with no guests coming over, has to outnumber the number of knocks resulting with a guest.

As much as desensitization may appear like an effective way to get a dog to become less reactive, it may not deliver the promising results as wanted. Pamela Reid in the book "Excelerated Learning" explains how a dog may appear to be desensitized to repeated doorbell ringing, but then should the door bell ring after a break of 20 minutes, the franctic barking starts all over. This is why I avoid using desensitization alone and prefer to power it up with classical counter-conditioning.
