The Pruritic/Hivey Horse: Allergies and Urticaria, and Ectoparasites

By Stephen D. White, DVM, DACVD

The Pruritic/Hivey HorseThe allergic skin diseases in the horse that are non-arthropod-bite related are atopic dermatitis (atopy), food allergy, and contact allergy. The history of the dermatitis is very important in determining which of these three is most likely in any particular horse. A seasonal pruritus, especially affecting the face and trunk, would be most consistent with atopic dermatitis to pollens; year-round pruritus would be more consistent with an atopic dermatitis as a reaction to molds or barn dust, or a food allergy. Episodes of pruritus that occur after topical treatments of shampoos, dips, etc. would be consistent with a contact allergy. The author finds true food allergy in horses to be very rare; this may be a reflection of practicing in a primarily referral practice, whereas cases of food allergy (real or presumed) are often diagnosed by the owner and/or the local veterinarian.
