Conditioned Emotional Response in Dog Training

A conditioned emotional response (CER) in dog training is an automatic emotional reaction a dog learns to have toward something because it has repeatedly been paired with something good or bad. For example, a dog that gets chicken every time it sees another dog can learn to feel happy, not nervous, when another dog appears. Trainers use positive CERs to change how a dog feels about triggers, which is the basis of counterconditioning for fear and reactivity.

In essence, CER is about feelings rather than commands. Teaching a dog to sit on cue is about behavior; building a CER is about making the dog feel a certain way when something happens. And once the feeling changes, the behavior often changes with it. Interested in learning more? Keep reading!

What is Conditioned Emotional Response (CER)?

Conditioned emotional response is a type of learning that comes from classical (Pavlovian) conditioning. It occurs when an animal or person repeatedly experiences a neutral stimulus, like a sound or a sight, just before something that naturally triggers an emotion, like food, play or pain. Over time, the stimulus alone triggers that emotion.

Pavlov's famous dogs drooled at the sound of a bell because the bell predicted food. In the same way, your dog may get excited when you pick up the leash (it predicts a walk), or start trembling at the sight of the car if car rides usually end at the vet.

CERs can be positive or negative. A positive CER makes your dog happy or relaxed when it notices something; a negative CER makes it fearful, anxious or upset. Dogs form them all the time without us trying, which is why many dogs love the sound of the treat jar and dread the sight of nail clippers.

In training, the goal is to build positive CERs on purpose and to replace negative ones. For a CER to form, the stimulus must be something the dog can easily notice, and the good thing must follow it consistently and quickly.

How Conditioned Emotional Response is Used in Dog Training

Conditioned emotional response can be a useful tool in dog training, particularly for fear, anxiety and reactivity, and for making training itself something your dog loves.

One of the most common ways that CER is used in dog training is through the use of a clicker. A clicker is a small device that makes a distinctive clicking sound when pressed.

Before a clicker means anything to your dog, trainers "charge" it by clicking and immediately giving a treat, over and over. That's classical conditioning: the click comes to predict good things, and your dog develops a happy, anticipating response to the sound. Once the click carries that positive feeling, trainers use it to mark the exact moment a dog does something right, for example the instant its bottom touches the floor during a sit.

Clickers work well because the sound is immediate and consistent, so dogs can easily recognize it.

The most powerful use of CER is counterconditioning: changing a negative emotional response into a positive one. Here, the treats don't depend on what the dog does. The trigger simply predicts the treats. Over time, the dog's feeling about the trigger shifts from "uh oh" to "yay, chicken!"

High-value treats work best for this, because the good feeling has to outweigh the dog's worry. Our list of the best training dog treats has good options.

How to build a positive CER to a trigger

1. Pick one trigger, such as other dogs, the doorbell, or the nail clippers.
2. Start below threshold. Begin at a distance or intensity where your dog notices the trigger but stays calm enough to eat.
3. Trigger appears, treats start. The moment your dog sees or hears the trigger, start feeding small, tasty treats.
4. Trigger disappears, treats stop. This makes the link clear: the trigger is what brings the good stuff.
5. Repeat and progress slowly. Over many short sessions, gradually move closer or increase the intensity, as long as your dog stays relaxed.

You'll know it's working when your dog sees the trigger and looks to you for a treat, with a soft, happy body. If your dog's fear or reactivity is severe, work with a qualified reward-based trainer or a veterinary behaviorist.

The Benefits of Using Conditioned Emotional Response in Dog Training

There are many benefits to using conditioned emotional response in dog training. Here are just some of the reasons that you should consider using CER in the training process of your dog.

Can Help Your Dog Learn Faster

A dog that feels happy and relaxed during training learns more easily than one that is stressed. When your dog has a positive CER to training itself, to you, the clicker and the training setting, it comes to sessions eager and engaged, which makes everything you teach go more smoothly.

For example, a dog that has learned the clicker predicts treats will perk up and pay attention as soon as you pick it up, ready to work.

Can Help Your Dog Learn More Effectively

In addition to helping your dog learn faster, CER can also help your dog learn more effectively, because it tackles the emotion behind a problem behavior. A dog that barks and lunges at other dogs out of fear will keep doing it as long as it feels afraid. Change the feeling, and the barking and lunging usually fade, too.

Research on dog training also suggests that reward-based methods work at least as well as punishment-based ones, without the side effects.

In contrast, punishment-based training methods often lead to short-term compliance but can result in long-term behavioral problems, such as aggression or fearfulness. Negative associations form the same way, which is one reason many dogs dislike getting their nails cut.

In other words, building positive CERs helps make sure your dog associates training, and the things it once feared, with good feelings rather than bad ones.

Let’s Recap

A conditioned emotional response is the automatic feeling your dog has learned to link with something in its world. By pairing triggers and training tools with good things, you can build positive CERs that make training easier and help fearful or reactive dogs feel safer. And if progress stalls, see why your dog may be regressing in training.
