What are common signs of a cold in horses?

Coughing, nasal discharge, and lethargy are typical indicators of a respiratory issue, often associated with colds in horses. When a horse has a cold, inflammation of the upper respiratory tract can lead to increased production of mucus, resulting in nasal discharge. This discharge can vary in consistency and color, helping to indicate the severity of the condition. Coughing is a natural reflex that occurs when the airways are irritated or blocked by mucus, making it an essential sign to watch for.

Lethargy, or a lack of energy, is another common symptom. When a horse is feeling unwell due to a cold, it may not exhibit its usual enthusiasm or energy levels. This decrease in activity can be a sign that the horse is not feeling its best and may require care and attention.

In contrast, signs such as lameness and heat in the hooves typically point to issues related to locomotion or injury rather than respiratory conditions. Restlessness and rolling are often associated with digestive discomfort or colic, which is unrelated to respiratory illness. A strong pulse in the digital arteries can signal an issue with circulation or inflammation but does not directly correlate with the common signs of a cold in horses.
