White Line Disease In Horses

White Line Disease (WLD), also known as seedy toe, hollow foot, wall thrush or stall rot, is a common equine hoof disease that can become serious if ignored. Clinical signs of the disease may vary from the horse not being lame at all to severe lameness with rotation of the distal phalanx. This is similar to that which can occur as a result of laminitis and depends on the extent of the disease affecting the inner hoof wall. If not caught early, white line disease can lead to months and months of intensive, time consuming treatment and in worse case scenarios, it can lead to extensive damage to the inner part of the hoof and the supportive tissues. The white line lies just inside the hoof wall and is not actually affected by its eponymous disease.

Treating White Line Disease with FormaHoof
Malva is a 17 year old draught mare. Was presented with a laminitis episode and subsequent severe white line disease in late September 2020. Her journey with FormaHoof allowed the transition to barefoot in January 2021.

What is White Line Disease?

White line disease is characterised by an invasion of bacteria and fungi that destroy hoof-wall tissue. The disease itself occurs secondary to a hoof wall separation and the opportunistic bacteria capitalise on any little defect in the hoof wall that will give these organisms a chance to get up under the hoof wall and grow in the non-pigmented horn. The outer surface of the wall may appear sound, but there is commonly a separation of the hoof wall from the underlying laminae. A hollow sound can be heard when tapping the outside of the wall at the affected area and in severe cases lameness may occur. As more of the hoof wall is damaged, the laminae that attach the coffin bone may also be compromised, allowing the bone to sink or rotate, causing a painful laminitis.

Is White Line Disease The Same As Thrush?

No, white line disease shouldn’t be confused with thrush. Thrush can be spotted by its foul smell and black tar-like discharge and although both are caused by bacteria and fungi, thrush is an infection of the frog, whereas in WLD these microorganisms invade the hoof wall, though it does not actually affect the white line itself.

What causes white line disease?

There can be a number of mitigating factors that cause white line disease, including improper trimming of the hoof horn by a barefoot trimmer or farrier, excessive amounts of concussive work on hooves that are less than healthy, poor hoof hygiene and husbandry, cracks in the walls and even nail-holes in the horse’s hoof wall which can lead to hoof infection. Other factors may include a less than desirable diet for the horse and wet living conditions may play a role, although WLD can also occur in horses in arid conditions.

How to Treat White Line Disease

In milder forms or early days, WLD does not cause lameness or any outward signs, but if an affected equine shows lameness,a veterinarian should be called in. X-rays can divulge how serious the problem is and will help your farrier in formulating a treatment protocol.


It’s important to act quickly at the first signs of WLD as with early and speedy intervention, white line disease can be cured. Here’s what your farrier will do:

Supporting The Hoof During White Line Disease Treatment And Growing a New Hoof With FormaHoof

Often, the resected hoof may benefit from being supported from remedial shoeing or a FormaHoof Application.

First and foremost, FormaHoof will stabilise the foot and help prevent the white line being stretched following a resection, whilst also providing a clean environment where no urine, faeces or dirt can enter the affected area.

Secondly, FormaHoof allows any required medications to be kept in place, without the need for daily, time-consuming bandage and wrap changes.

And thirdly, FormaHoof will help to promote healthy hoof growth as the entire hoof can continue to bear full weight, improving blood flow and healing.

An added benefit is the fact that horses can return back to training earlier that would otherwise have been the case, or even continue training throughout treatment in the FormaHoof application, rather than an often lengthy convalescence period being required.
