Warmblood Fragile Foal Syndrome (WFFS)

The Warmblood Fragile Foal Syndrome is a hereditary disorder that has been recognized in the United States for several years. A foal with WFFS can be aborted, be born prematurely and/or be born with abnormalities. The most important abnormalities in the newborn foal are: skin abnormalities (such as too elastic skin that tears easily, wounds that 'just' occur) and hyperextension of joints. Usually the animals will die within 1-2 weeks of birth or they need to be euthanized.
