Founder - Chronic founder means he will always have foot problems with that leg, and will occasionally cross the line to full blown laminitis on occasion. Founder is when there is an inflammation in the blood vessels and tissues that surround and help adhere the coffin bone to the hoof. Laminitis is when those tissues start to break down and the coffin bone pulls away from the hoof, starts to rotate, and then sink down through the bottom of the hoof. Founder is very painful and if not addressed properly and immediately, it will lead to laminitis which typically has a very guarded prognosis.
The x-ray will show if the coffin bone is rotating as in laminitis. A horse with chronic founder and laminitis problems may show a displaced coffin bone (sunken) caused by past problems. Founder is usually detected by severe pain in the hoof, increased digital pulses, and heat from the hoof.
Horses can founder from various causes, too much fresh grass, too much grain, hard concussion from running on hard ground, foaling and retaining the placentia, too long riding in a trailer and not being able to move around, just to name a few.
