Equine diseases refer to various health conditions that affect horses, impacting their overall well-being and performance. Common diseases include colic, which causes abdominal pain, and laminitis, an inflammation of the hoof. Other notable conditions are equine influenza and strangles, both of which are contagious and can spread rapidly among horses. Preventative measures, such as vaccinations and regular veterinary check-ups, are essential for maintaining horse health. Owners should also be aware of signs of illness, including changes in appetite, behavior, or physical appearance. Early detection and treatment can significantly improve outcomes for affected horses.
