For many years, intradermal allergy testing has been considered the gold standard for diagnosing and treating canine atopy, and it remains the primary testing method used by most veterinary dermatologists. Intradermal allergy testing permits testing of the skin where the allergic response is occurring. Most animals tolerate the procedure well, and the results are immediately available usually within 5-15 minutes. Animals are sedated to minimize anxiety and stress, then shaved along the chest wall and injected intradermally with approximately 62 allergens. In order to be considered for skin testing, the dog needs to be withdrawn from antihistamines for 10-14 days before testing and all steroid containing medications for at least 4 weeks prior to testing.
