Equine atopic disease may be seasonal or non-seasonal, depending on the allergen(s) involved. Similar to other species, the disease may start off more seasonal but progress to more year round disease with seasonal intensity. Pruritus, often directed against the face, distal legs, or trunk, is the most common clinical sign. However pruritus can be more generalized and mimic insect hypersensitivity distribution patterns. In some cases, the urticaria lesions are associated with pitting oedema, most typically seen over the ventral thorax. Most food-allergic horses would classically be considered when presented with non-seasonal pruritic disease or urticarial signs. Pruritus and urticaria may be seen on parts of the body less likely to be affected by an insect hypersensitivity and would include the lateral caudal thorax and flanks. Pruritus limited to the base of the tail would also increase the consideration of an adverse food reaction.
