The Equine Respiratory system shuttles air to and from a horses’ lungs where respiration, the exchange of oxygen for carbon dioxide, occurs. This is a highly specialized organ system that can move large volumes of air in and out of the lungs each minute. The respiratory system is made up of the upper and lower airways. The upper airway contains the nasal passage, pharynx, larynx, and trachea. The lower airway hosts the lungs.
Did you know the horse does not breathe through its mouth and nose like we do?
Your horse can only breathe through its nostrils. The nose and the mouth are entirely separate - a horse will only breathe through their mouth if there is something wrong with the soft palate that separates the mouth from the nose.
Fun fact: At rest the horse inhales approximately 16 gallons per minute. At the gallop this increases to a phenomenal 600 gallons per minute!
The lungs are the most essential organs of the respiratory system; the rest are passages carrying air into the lungs. In the lungs, oxygen is removed by diffusion into the blood. It’s important to be aware of the potential respiratory system problems that are found in horses to best care for your horse. Any problem with the structure or function of the respiratory system can cause exercise intolerance, poor performance, and ultimately negatively impact quality of life.

6 Best Barn Management Tips for Better Breathing
Considerable short and long-term demands are placed on the equine lungs. Special attention must be paid to the quality of the air, which our horses breathe. Pharmaceuticals will continue to play an important role in the treatment of respiratory problems but prevention is better than cure.
Wet all hay that is fed indoors and feed close to ground level or feed a good quality, low dust alternative forage product.
Remove the horse from the barn when mucking.
Sprinkle the barn aisle with water when sweeping or raking.
Use a quality bedding and muck out daily (avoid deep litter systems).
Edema in horses is the accumulation of fluid somewhere in their bodies, most commonly in their legs (commonly known as “stocking up”) or in their lower abdomen. Edema is different than inflammation and, in rare cases, can become malignant and even fatal. Read on to learn about common forms of edema in horses and what you can do to help.
Essential oils are an excellent natural home remedy for wounds or your dog’s irritated skin. However, not all essential oils are safe to use around or on dogs. Make sure you know what is helpful and harmful before using any essential oils on your dog.
Hearts are an amazing thing in all animals. A constantly working muscle, the heart, pumps blood throughout the body to sustain life. The horse’s heart is a well-oiled machine—the heart’s efficiency results in a super athlete.
