About noise phobia and solutions

Prevalence of noise phobias:

In 2013, Blackwell et al. conducted a research study to determine the prevalence of noise phobias in pet dogs. Almost half of the owners in the study reported that their dog showed at least one behavioral sign typical of fear when exposed to noises. An estimated of 29% of pet dogs show signs of anxiety-related behaviors (Denenberg et al., 2013), and 17% to 49% of all dogs have been estimated to demonstrate an aversion to noise (Blackwell et al., 2013).

Pathophysiology:

Physiological signs of a stress response, such as elevated cortisol, have been identified in dogs showing behavioral responses to noises (Hydbring-Sandberg et al., 2004). In many species, a physiological stress response occurs following exposure to a fear or anxiety-provoking stimulus. If anxious or fearful animals produce a stress response to many day-to-day stimuli, it follows that they may also live in a state of chronic physiological stress. Stressor activates the hypothalamic–pituitary–adrenal (HPA) system and increases the levels of cortisol in the blood stream. This leads to a series of adverse health effects like cardiovascular disease, immune disturbances, altered endocrine responses, obesity, insulin resistance and nervous system disorders. A study conducted by Dreschel in 2010 demonstrated that the stress associated with fear and anxiety can adversely affect health and lifespan of animals.

Current treatments:

Psychoactive drugs, including benzodiazepines, azapirones, antidepressants and selective serotonin reuptake inhibitors, are commonly prescribed in the treatment of fear and anxiety disorders in animals (Overall, 2013; Landsberg et al., 2013).

Fluoxetine and clomipramine are the only drugs licensed for anxiety treatment in dogs, however, these drugs can take a month or longer to achieve their full therapeutic effects and some owners are hesitant or unwilling to use these medications because of the potential for side effects or personal bias against psychotropic drug use (Landsberg, 2015). There are also various nutritional supplements marketed for behavior therapy, but very few have demonstrated any evidence of efficacy.

Advantages of the WeStopFear Method:

WeStopFear™ is based on the methods of desensitization and habituation, in which the stress-causing sounds are played with a gradual increase of volume in order for the animal to get used to these sounds. Unlike treatment with antidepressants and anxiolytics, this treatment is completely safe and there are no adverse health effects. Desensitization and habituation methods have been widely studied (Watts, 1971; Watts, 1979 & Lader, 1968) and are proven to be effective in the management of behavioral problems in animals.
