Bottom Line
Allergies are a serious medical problem that causes a great deal of suffering for pets and their owners. Causes are complex and involve both genetic, developmental, and environmental factors, and symptoms tend to come and go unpredictably, which makes evaluating the effects of any particular intervention challenging. While there are many safe and effective therapies that can help manage allergy symptoms, there is no cure. Only complete avoidance of the antigens the individual is allergic to can eliminate symptoms entirely, and this is often not possible. No treatment that has any benefit is completely without risks, and the risks and benefits must always be carefully and rationally weighed.

The variability and chronicity of the symptoms and the complexity of the causation create fertile ground in which to sow myths and misconceptions about causes and treatments, as this article does vigorously. Providing treatments based on sound scientific understanding of the physiology of allergies and supported by reliable scientific evidence of safety and efficacy is the best way to help patients with this serious condition. Myths about allergy causes and treatments that are without a rational, scientific foundation or any real evidence of safety and efficacy are not legitimate “choices” or “options” to offer pet owners looking for real help. Integrating unproven methods and outright nonsense with established allergy therapies doesn’t add value or reduce risks, it diminishes our ability to help these patients and their human families.
