Legs

Before (or directly after) purchasing your Friesian, get baseline leg and hoof x-rays of anything 1 year and older. (less than one year is arguable, but if you're not suspcious of anything, I personally don't see a need). Try to x-ray at least hooves/lower legs annually. Friesians are prone to extensor process fractures and lower leg bone chips in general, due to their size and generally high-kneed, high impact movement. It's best to monitor your horse's front legs for any coffin bone changes/chips and hocks/stifles for OCD, especially in younger horses. ALWAYS get x-rays before you buy. ALWAYS. If a seller does not allow you to do so, WALK AWAY. Friesians are hard on their legs and hooves due to their movement, so if you are buying a middle aged or older friesian, you are more likely to find a chronic problem that will not show up in a standard vet exam and will need to be addressed later to maintain their soundness.
