DESENSITIZATION: ARE YOU DOING IT RIGHT?
Some thirty years ago when I was in graduate school, I was interested in taking a course in animal learning which involved working in what I call a "rat lab." The lab was run by one of the university's psychology professors who did learning experiments on rats.
But I wasn't sure I could handle a rat, so I contacted the professor and explained my situation. He invited me to come to the lab and I went right down.
When I arrived at the lab, the professor offered m a seat at a long, narrow table adjoined to the wall. The professor excused himself and he soon returned with a baby white rat. He carefully handed me the rat, and I held it for a short time as we talked. It was kind of cute, certainly not scary or hard to hold.
After holding the baby rat for a little while, the professor excused himself again and returned with a somewhat larger rat. He handed me the rat and I held it for a while as we continued talking.
This process continued. Each time the professor returned with a slightly larger rat, and each time I held the rat, barely noticing the size difference.
Now, these rats were domestic, lab-bred and raised rats that were more or less friendly, depending on how much they were handled and their individual personalities. Most were agreeable, but since they were albinos with white eyes, they had poor vision, and occasionally one would bite a finger, only because human fingers were about the same size as the high value food reinforcement we gave them.
At the conclusion of this process, I not only felt differently about rats, but I understood the process of desensitization better. I completed the semester in that lab, and at the end of the semester, students were allowed to adopt one of the rats, if we wanted. I chose not to.
Although I learned to be less afraid of rats enough to handle them, I didn't exactly grow fond of them.
However, years later when I was volunteering in an animal shelter and a domestic pet rat was surrendered, I found myself eager to pick the rat up and interact with it. I still wasn't interested in adopting a rat, but I had no fear and had a positive emotional response to the furry little critter.
I feel the same today. Recently, I've had the opportunity to be close to and interact with domestic rats, and I still have no interest in owning one, but I still have no fear. Again, these were domestic rats. I would not have the same emotional response to a wild rat.
So, the effect of desensitization can be long lasting if done correctly.
If done incorrectly, desensitization can not only be ineffective; it can further sensitize, rather than desensitize a person or an animal. Had one of those rats bitten me, I might have aborted the process and decided not to enroll in the class. Further, being bitten would have justified my fear of rats and made me even more afraid of them.
When we do desensitization with our dogs to a feared object or situation, it's essential to avoid causing any fear or anxiety, and to allow the dog to make choices. You should NEVER force a dog to deal with his fears and never ask him to deal with his fear at full intensity.
We usually speak of counterconditioning when talking about desensitization. The two go hand in hand. Counterconditioning is creating a positive response to the feared object by pairing it with something pleasant, usually food. In my experience at the rat lab, counterconditioning was achieved by holding a small furry animal that was friendly and cute.
Done correctly, you should never see a reaction in your dog during desensitization. Only proceed at a pace that allows your dog to continue to feel comfortable. If you progress too quickly and see a reaction in your dog, you are further sensitizing, rather than de-sensitizing him to the object of his fear.
Done correctly, you can help your dog overcome his fear by creating a new, neutral or more positive emotional response to a feared object, but done incorrectly, you will get nowhere, and run the risk of making his fear worse.
