What are two common symptoms of a cold in horses?

The presence of coughing and nasal discharge are indeed common symptoms of a cold in horses, which typically indicate upper respiratory tract issues. Coughing can occur due to airway irritation or inflammation, and nasal discharge is often a sign of mucous production resulting from congestion or infection. Together, these symptoms can help differentiate a simple cold from more severe respiratory conditions.

High fever and reluctance to eat are generally associated with more serious illnesses, such as infectious diseases or systemic issues, rather than a standard cold. Excessive sweating and lethargy might also indicate an underlying problem but are not specific to colds. Similarly, rapid breathing and weight loss indicate chronic issues rather than the typical symptoms of a cold. Thus, coughing and nasal discharge are the most accurate indicators for a cold in horses.
