A young foal with a swollen leg is an emergency. There are many potential causes for leg swelling, but the most serious is a septic (infected) joint, which requires immediate veterinary attention. Horse owners often incorrectly attribute swelling or lameness to traumatic injury by the mare, but this is actually very uncommon. What is more common is joint infection, which is life-threatening.

WHAT TO DO

Keep the mare and foal in a small corral until a vet can examine them. Before the vet arrives, assess the foal’s attitude and appetite. Take the foal’s rectal temperature, if you can do so easily and with confidence. Take note of the appearance of the umbilicus and consider whether you have noticed any diarrhea.

Share your findings and concerns with your vet.

WHAT YOUR VET DOES

Your vet evaluates a leg swelling to rule out septic joint or tendon sheath. This requires physical examination and a variety of other diagnostic tests. Confirmation may require needle sampling of the joint fluid for infection. A proper diagnosis is critical to the life of the foal.

What Not To Do

Do not assume that a swollen joint or leg in a foal is a traumatic injury. Instead recognize the danger and risk of septic joint and promptly discuss the problem with your vet.

Do not handle the foal if you are not confident in doing so.
