Respiratory Distress
Respiratory distress is one of the common symptoms of horse allergies. This can manifest as coughing, wheezing, rapid or laboured breathing, and over time may result in exercise intolerance. This typically occurs when the horse is allergic to inhaled substances like dust or mould.
Itching and Skin Irritations
Itching (pruritus) around the mane, tail, and underbelly is commonly observed in horses with allergies. Inflammation, bald patches, hives, redness, and scabs may emerge as the horse consistently scratches or rubs these areas against surfaces.
Watery, Red Eyes
Allergies in horses can lead to ocular symptoms which include watery, red, or swollen eyes. There may be also excessive tearing (epiphora) or the development of a discharge.
Increased Gut Sounds and Diarrhea
If the allergy is related to something the horse has ingested, increased gut sounds (borborygmi) may be noticed. This could also lead to diarrhea, and less commonly, colic.
Feeding Changes
Horses with an allergy might show changes in their feeding habits due to oral discomfort or gastrointestinal issues. This can be loss of appetite, difficulty swallowing, or increased thirst.
Behavioural Changes
Horses experiencing discomfort due to allergies might exhibit behavioural changes. These changes could include restlessness, irritability, aggression, or signs of depression. These are more likely due to discomfort from the physical symptoms rather than a direct result of the allergy itself.
