Management and treatment

How do providers treat cynophobia?

The primary treatments for cynophobia are therapy and medication. There are several types of therapy that can help people with an overwhelming fear of dogs. These include:

Exposure therapy 

Your provider gradually exposes you to dogs. Some providers offer virtual reality therapy using special goggles that mimic interacting with a real dog. Over time, your sensitivity to dogs decreases and you become less fearful. This therapy may include:

  1. Closing your eyes and imagining an encounter with a dog.
  2. Seeing pictures or videos of dogs
  3. Holding a toy dog
  4. Watching dogs play from a distance and slowly getting closer to the dog.
  5. Petting a dog while it’s on a leash
  6. Spending time with a dog off a leash.

This is also called desensitization. In simple terms, persons undergoing exposure therapy practice interacting with the objects that they fear.

  • To treat cynophobia, some therapists suggest that you gradually increase both the closeness and length of your exposure. You could start by watching programs that feature dogs or watching dogs from a distance. Then, you work up to spending periods of time with dogs in person.
  • Another form of exposure therapy with some proven success is called active-imaginal exposure. In this style of treatment, you would vividly imagine interacting with dogs and practice using certain techniques to manage your feelings in response.

Virtual reality exposure

More recently, many therapists have had success with virtual reality exposure. Both sound and sight elements are combined in a virtual reality experience. This gives the person practice being around dogs in a safe and controlled environment.

Your provider may also recommend:

Cognitive behavioral therapy (CBT) 

Cognitive behavioral therapy (CBT) to change the way you respond to fear and think about dogs in a different way.

Psychotherapy, or talk therapy, to help you understand your fears.


Hypnotherapy which includes guided relaxation exercises while your mind is in a calm state. This allows you to rethink your fear of dogs and the anxiety it causes.

Mindfulness exercises, yoga, breathing exercises and meditation to help you control anxiety.


  • Medications to treat depression, relieve anxiety or control panic attacks.
  • The impact of drugs on specific phobias has been inconsistent. They appear to work best when used with exposure therapy instead of on their own. However, some anti-anxiety medications such as beta-blockers and sedatives can help you treat the physical symptoms of severe attacks.
  • More recently, researchers have discovered that a steroid called glucocorticoid can successfully decrease the physical symptoms associated with the anxiety connected to specific phobias. This includes the fear of dogs.

‌Several forms of therapy have helped people with cynophobia. Consult your doctor or a licensed mental health professional to find the right treatment or combination of treatments.

What are the complications of cynophobia?

Without treatment, severe cynophobia can cause people to avoid situations where they may encounter dogs. They might stay away from family and friends or stop going for walks outside. They may even develop agoraphobia and stop leaving their home altogether. This can damage relationships and lead to problems holding down a job. Isolation, anxiety and depression can result.

Outlook / prognosis

  2. How do you stop cynophobia?
  3. What type of therapy or treatment is right for me?
  4. What experience do you have with exposure therapy and CBT?
