Fear comes in all shapes and sizes, especially for your furry, four-pawed friend. Whether in response to a stranger or startling noise, your dog may display certain body postures, including lowering his head, flattening his ears back against his head, and tucking his tail between his legs if he’s scared.

A frightened dog may also pant, salivate, tremble, pace, or try to escape. He may show submissive behaviors— avoiding eye contact, urinating submissively, or rolling over to expose his belly—or he may freeze and remain immobile. Some dogs will bark or growl at the feared object. In extreme cases of fearfulness, a dog may be destructive (out of general anxiety or in an attempt to escape), or he may lose control of his bladder or bowels.

Causes of Fearful Behavior

Determining why your dog is fearful is helpful but not always essential to treating the fearful behavior, although the reason for his fear will dictate the relative success of the treatment. A dog who is genetically predisposed to general fearfulness, or a dog who was improperly socialized during a critical stage in his development, will probably not respond as well to treatment as a dog who has developed a fear in response to a specific experience.
It’s essential, however, to first rule out any medical causes for your dog’s fearful behavior. Your first step should be to take your dog to your veterinarian for a thorough medical evaluation.

What You Can Do

Most fears won’t go away by themselves and, if left untreated, may get worse. Some fears, when treated, will decrease in intensity or frequency but may not disappear entirely. After you’ve ruled out medical causes, your first step in dealing with your dog’s fearful behavior is to identify what triggers his fear. Is he afraid of startling noises? Is he afraid of being left alone? If your dog’s fears are rooted in either of these scenarios, see our related tip sheets on these topics. Most fears can be treated using desensitization and counterconditioning techniques, which require time and patience.

How to Use the Desensitization Technique

Begin by exposing your dog to a very low level or small amount of whatever is causing his fear. For example, if he is afraid of bicycles, start with a bicycle placed at a distance of 100 feet from your dog. Reward him for calm, nonfearful behavior in the presence of the bicycle. Gradually move the bicycle closer to him. As long as your dog remains relaxed, reward him with treats and praise. If at any point he becomes anxious, move the bicycle further away and proceed at a slower pace. When your dog can remain relaxed in the presence of a stationary bicycle, move the bicycle 100 feet away again, but have someone ride it slowly by him. Again, gradually increase the proximity of the slowly moving bicycle, rewarding your dog for remaining calm and relaxed. Repeat this procedure as many times as necessary, gradually increasing the speed of the moving bicycle.

This process may take several days, weeks, or even months. You must proceed at a slow enough pace that your dog never becomes fearful during the desensitization process. If you move too quickly, you won’t be successful.

How to Use the Counterconditioning Technique

Counterconditioning works best when used in conjunction with desensitization and involves pairing the fear stimulus (for example, a moving bicycle) with an activity or behavior incompatible with the fear behavior (for example, the dog remaining in the "sit" position). Using the desensitization technique example described previously, while your dog is exposed to the bicycle, ask him to perform some obedience exercises, such as "sit" and "down." Reward him for obeying and continue to have him obey commands as the bicycle is moved closer to him.

If your dog doesn’t know any commands, teach him a few using treats and praise. Don’t ever use punishment, collar corrections, or scolding to teach him the commands, because the point of counterconditioning is for him to associate pleasant things with the stimulus that now frightens him.

Realistic Expectations

Some of the things that frighten dogs can be difficult to reproduce or control. For example, if your dog is afraid of thunderstorms, he may be responding to other things that occur during the storm, such as smells, barometric pressure changes, or changes in natural light. During the desensitization process, it is impossible for you to reproduce all of these factors. Another example would be if your dog is afraid of men. You may work at desensitizing him, but if a man lives in your household and your dog is constantly exposed to him, this can disrupt the gradual process of desensitization. You need to be patient with your dog and work hard not to become frustrated during the desensitization process.

When to Get Help

Because desensitization and counterconditioning can be difficult techniques to master, and because behavior problems may increase if these techniques are done incorrectly, you may want to contact a trainer to set up a consultation. Keep in mind that a fearful dog who feels trapped or is pushed too far may become aggressive. Some dogs will respond aggressively to whatever it is that frightens them. If your dog displays any aggressive behavior, such as growling, snarling, snapping, or baring his teeth, stop all behavior modification procedures and seek professional help from an animal-behavior specialist as soon as possible.

Consult With Your Veterinarian

Medication may help reduce your dog’s anxiety levels for short time periods. Your veterinarian is the only person who is qualified and licensed to prescribe medication for your dog. Don’t attempt to give your dog any over-the-counter or prescription medication without consulting with your veterinarian. Animals don’t respond to drugs the same way people do, and a medication that may be safe for humans could be fatal to your dog. Drug therapy alone won’t reduce fears and phobias permanently, but in extreme cases, behavior modification and medication used together may be the best approach.

What Not to Do

• Do not punish your dog for being afraid. Punishment will only make him more fearful.
• Do not try to force your dog to experience the object or situation that is causing him to be afraid. For example, if he is afraid of bicycles and you force him to stand in place while bicycles whiz by, he’ll probably become more fearful of bicycles rather than less fearful.
• Never punish your dog after the fact for destruction or house soiling caused by anxiety or fear. Animals don’t understand punishment after the fact, even if it’s only seconds later. This kind of destruction or house soiling is the result of panic, not misbehavior. Punishment will do more harm than good.
