With the weather changing in most parts of the country, beware the horse that’s coughing.

It could be just a mild infection, or it could be something more serious. To make sure your veterinarian has good information should you need to call him to the farm, start by observing your horse.

Notice when he coughs: Is it immediately after eating? At the beginning of a ride? Or during the entire ride? Maybe you’ve just heard one or two coughs during the day.

Take your horse’s temperature: Anything above 101 is a reason to call your veterinarian.

Also notice the quality of the cough: Is a deep cough or more of a dry cough? Check you horse’s respiration rate by counting his exhales for 15 seconds. Then multiply that number by 4. If his rate is over 20 (normal is 10-20) he may be in some distress. Call the vet.

Some horses develop chronic coughs and allergies, just as humans do. If a cough continues for more than three weeks and there is no sign of bacterial or viral infection (other symptoms such as a runny nose and a fever) he may have a stable cough or an allergy. Your veterinarian can provide a clear diagnosis and offer treatment options.
