What is HYPP in Horses?

Updated July 6, 2024

In this Ask the Vet video, Dr. Lydia Gray and SmartPaker Sarah talk about Hyperkalemic Periodic Paralysis in horses, more widely known as HYPP. Dr. Gray explains HYPP's origins with the Quarter Horse sire Impressive, signs that your horse may have this muscular condition, plus what to feed (and what NOT to feed) horses that have been diagnosed.

SmartPak strongly encourages you to consult your veterinarian regarding specific questions about your horse's health. This information is not intended to diagnose or treat any disease, and is purely educational.
