Laminitis (also called Founder) means inflammation of the soft tissue structures (Laminae) inside the hoof. The Laminae attaches the foot bones (pedal bone) to the hoof itself. When the Laminae become inflamed it gets very sore and the horse becomes lame, it also causes instability in the attachment of the hoof to the bone. In very severe cases it may cause death.

Once a horse or pony has had Laminitis it becomes more susceptible to future episodes of the illness. Laminitis can be treated but there is no cure, so prevention is very important.

Causes: Overweight horses and ponies, particularly during the spring months after recent rain. When too many carbohydrates have been ingested their metabolic changes result in altered blood flow to the laminae of the foot. Other causes may include over feeding grain, excess work on hard ground, hoof trimming too short.

Symptoms: All 4 feet can become laminitc, horses may become lame, or not want to move and seem to rock as they shift their weight between less sore limbs and lying down a lot. The hoof and coronary band are warm to touch with strong and rapid digital pulses.

Prevention: Ensure your horse or pony is fed a balanced ration appropriate for their type, age and activity level. Restrict access to lush pasture particularly during the wet spring months. Ensure your horse receives regular hoof care from a reputable farrier.
