Most Common Horse Diseases

Navicular, founder, EPM, Cushing's and COPD are potentially life-threatening equine diseases. With early treatment, afflicted horses can go on to lead normal lives.

Navicular Disease

Navicular disease, a chronic degenerative condition, is a cause of lameness. Confirmed by hoof X-rays, first signs are stumbling and standing with pressure off the heel.

Founder

Founder, or laminitis, occurs when the coffin bone pulls away from the sole due to inflammation and fluid collection in the laminae. The prognosis depends on how early the founder is detected and how far the coffin bone has rotated.

EPM

Equine protozoal myeloencephalitis (EPM) attacks the brain and spinal cord. Horses acquire the disease through grazing fields contaminated with infected opossum droppings. Muscular wasting, personality changes and abnormal gaits are hallmarks of EPM.

Cushing's Disease

Cushing's, a pituitary problem affecting older horses, can be managed when detected early. It is first suspected when a horse is slow to shed, loses weight and drinks excessively.

COPD, or Allergic Lung Disease

Allergic lung disease, or COPD, is very similar to asthma in humans. If left untreated, the lungs may be permanently damaged, resulting in "heaves." Medications can be used to improve the quality of life for the COPD horse.
