It fills any pony owner with dread. But it is not a problem that is prevalent in just overweight ponies; there are a number of causes that with careful management can reduce the risk of laminitis.
Laminitis is inflammation of the laminae, which attaches the hoof to the pedal bone, once this is damaged the pedal bone can drop and, or rotate. This can be incredibly painful and causes a lot of distress to the horse.
Be aware of the signs of laminitis, as the likelihood is that the clinical symptoms will be seen when the laminitis has really taken hold.
• Poor performance, reluctance to move forward or not wanting to jump
• Fatty distension of the crest
• Weight gain
• Shortening of stride when trotted on hard ground
• Frequent weight swapping from one foot to the other
• Strong, rapid digital pulse
• Laminitic stance-weight in its heels
• Wants to lie down or take weight off its feet.
Chronic cases:
• Lameness, particularly on hard ground
• Footsore, red bruising when feet are trimmed
• Pus in foot
• Odd shaped feet, including rings on the hoof wall, long toes, dropped soles and wide white lines and flat feet.
Laminitis can be caused by a number of reasons:
• High carbohydrate diet: Causing rapid fermentation in the hind gut.
• Colic stress
• Retained placenta- toxaemia
• Mechanical overload: concussion through hard, fast work on hard surfaces (road founder)
• Hormonal problems: (good doers) hyperthyroid, abnormal peripheral cortisol enzyme system or even when some horses come into season it can trigger laminitis attacks.
What to do when laminitis is diagnosed:
• Vet: they will examine the horse and provide adequate drugs (possibly Bute or ACP) to help relive any pain or discomfort.
• Remove the horse form the source of the problem, either feed or field.
• Keep the horse comfortable with a deep bed (preferably shavings) to encourage lying down.
▪ Get in contact with the farrier to liaise with the vet to sort shoeing, they will probably need x-rays in order to give maximum frog support.
• Do not feed the horse until the vet has been.
Laminitis is a disease that will require the horse owner to monitor the horse especially during times when an attack of laminitis is likely to occur.
