Equine founder and laminitis are very similar forms of the same disease. Founder is basically the end stage of laminitis. This disease is extremely painful to horses and may develop in all four legs. However the front legs are the most commonly affected. Foundering occurs when the coffin bone eventually detaches from the damaged laminae. In extreme cases the coffin bone will rotate downwards and push through the hoof sole.

The causes of this disease are:

	Obesity
	Feeding too much grain
	Drinking cold water when the horse’s body temperature is elevated
	Sudden access to lush pasture
	Retained Placenta
	Colic

The common symptoms are:

	Standing with front legs out while putting weight on the heel to alleviate pressure
	Prefers laying down
	Digital pulse becomes present

If foundering is suspected, Dr. Winter should be called immediately. If caught early enough, he is able to perform a series of IV treatments which aids in preventing further damage. In most cases, foundering can be prevented and proper owner management is essential.
