B) walk him around, slowly.

C) call your veterinarian.

HOW’D YOU DO? (Answers below.)

1. T is correct. Laminitis, also known as founder, can strike any horse, even famous ones. Because it’s so painful, it can be hard—sometimes even impossible—to break the cycle of laminitis once it begins. Early detection is key.

2. A is correct. The pain is caused by an increased resistance to blood flow inside the horse’s feet as the cells of the lamellae separate from the basement membrane and small blood vessels called capillaries are drawn away.

3. F is correct. Grade 3 laminitis can occur suddenly (a complete separation of the lamellae from the basement membrane can happen as fast as 48 hours after the process begins) or gradually over time. In either case, the pain is constant and excruciating.

4. C is correct. Get your vet on board immediately to begin treatment that can minimize damage to your horse’s feet. Your vet may direct you to stand your horse in buckets of ice water while you wait for his or her arrival; studies have shown that icing is very effective for minimizing the progression of the disease in its early stages. At this point, limit your horse’s movement.
