Horses can suffer from various diseases that affect their health and performance. Common conditions include colic, which causes abdominal pain, and laminitis, an inflammation of the hoof's sensitive tissue. Other diseases, such as equine influenza and strangles, are contagious and can spread quickly among horses. Preventative care, including vaccinations and regular veterinary check-ups, is essential for maintaining a horse's health. Owners should also be aware of signs of illness, such as changes in appetite or behavior, to ensure prompt treatment. Proper nutrition and exercise can help reduce the risk of many horse diseases.
