Laminitis in Donkeys: Signs, Causes, and What Owners Often Miss

By Dr Duncan Houston

Laminitis in donkeys is often missed because it does not always look the way people expect.

Most owners are taught to think about laminitis as a horse problem, usually linked to rich pasture, obvious foot pain, and a dramatic stance. Donkeys do get laminitis, but they often show it differently, and that difference is where mistakes happen.

In practice, donkey laminitis is frequently more chronic, more subtle, and more easily overlooked until significant hoof damage has already developed.

Quick Answer

Donkeys do develop laminitis, and it is often chronic rather than sudden. The signs may be subtle, such as reduced activity, stiffness, abnormal hoof growth, or reluctance to walk on hard ground. Prevention depends on careful hoof monitoring, weight and metabolic management, soft footing, and early veterinary assessment when anything changes.

Why Laminitis in Donkeys Is Different

Laminitis in donkeys does not always follow the classic horse pattern.

In horses, people often expect:

• sudden pain

• obvious heat in the feet

• a rocked-back stance

• a clear link to rich grass or grain

In donkeys, the picture is often more muted.

They may show:

• gradual stiffness

• reduced willingness to move

• subtle gait shortening

• chronic hoof distortion over time

The biggest issue is that donkeys are often far less expressive with pain. That means owners may see a donkey as quiet or slowing down, when in reality it is already uncomfortable.

Do Donkeys Really Get Laminitis?

Yes. Donkeys do get laminitis, and in some populations it appears to be very common.

What matters clinically is not just whether laminitis occurs, but that many donkey cases are:

• chronic

• recurrent

• less obvious in the early stages

This is why donkey laminitis is often diagnosed later than it should be.

What Causes Laminitis in Donkeys

The causes overlap with horses, but the patterns are not always the same.

Potential contributors include:

• metabolic dysfunction

• PPID

• weight gain

• inappropriate nutrition

• chronic hoof imbalance

• time spent on hard surfaces

• reduced movement or environmental change

One important difference is that donkey laminitis is not always tied to obvious overfeeding. Some donkeys affected by laminitis are not grossly overweight and may not be on lush pasture at the time signs appear.

That is why relying only on the usual horse risk factors can lead to missed cases.

Why Hard Surfaces Matter More Than People Think

One of the most useful clinical observations in donkeys is that signs may become more obvious when they are housed on hard ground.

Hard flooring can:

• increase concussion

• highlight foot pain

• reduce comfort

• make a mildly lame donkey look significantly worse

In practice, some donkeys are first recognised as laminitic not because they suddenly worsened, but because the environment exposed the pain that was already there.

How Serious Is It?

Mild

• slight stiffness

• reduced activity

• subtle shortened stride

• mild reluctance on hard ground

What this means: early or low-grade laminitis may be present.

What to do: reassess immediately and arrange veterinary evaluation if signs persist.

Moderate

• clear reluctance to move

• altered hoof shape

• more obvious stiffness

• reduced comfort turning or walking on firm surfaces

What this means: active or chronic laminitic change is likely.

What to do: veterinary assessment is recommended promptly.

High Risk

• worsening mobility

• abnormal hoof growth rings

• chronic foot pain signs

• recurring episodes of soreness

What this means: structural hoof damage may already be developing.

What to do: full assessment, including imaging, is often needed.

Severe

• marked pain

• inability or reluctance to walk

• obvious hoof distortion

• concern for rotation or sinking

What this means: this is an urgent veterinary problem.

What to do: immediate veterinary care is needed.

The Signs Owners Commonly Miss

This is where donkey cases go wrong.

Owners often look for dramatic signs and miss the quieter ones.

Common early signs include:

• walking less

• standing more

• subtle stiffness

• reluctance on firm or stony ground

• shortened steps

• hooves that look increasingly misshapen

• chronic overgrowth or abnormal hoof rings

A donkey with laminitis may not look dramatic. It may just look "not quite right" for weeks or months.

Acute vs Chronic Laminitis in Donkeys

Acute laminitis

This looks more like the classic emergency picture:

• sudden pain

• reluctance to move

• increased foot sensitivity

Chronic laminitis

This is more common in many donkeys and may show as:

• long-standing hoof distortion

• repeated mild soreness

• reduced activity over time

• gradual change in posture and gait

In practice, chronic cases are the ones most often missed because owners adapt to the donkey’s slower, more careful movement without realising what it means.

The Role of PPID and Metabolic Disease

PPID matters in donkeys just as it does in horses.

You should think about PPID if a donkey also shows:

• coat changes

• lethargy

• increased drinking

• increased urination

• repeated laminitis episodes

If PPID is present and not managed, the risk of recurrent laminitis goes up significantly.

This is one of the most important rule-outs in adult and older donkeys with repeated hoof pain.

What To Do Right Now If You Suspect Laminitis

If you think your donkey may be laminitic:

1. Remove access to high-risk feed sources
   Avoid rich pasture and energy-dense feeds until the situation is assessed.

2. Move onto softer footing
   Deep bedding or softer surfaces can make a major difference to comfort.

3. Reduce unnecessary movement
   Do not force exercise in a painful donkey.

4. Check the hooves carefully
   Look for abnormal growth, distortion, rings, or signs the feet are becoming misshapen.

5. Call your vet early
   The earlier laminitis is diagnosed, the better the long-term outcome tends to be.

How Vets Diagnose Laminitis in Donkeys

Diagnosis is based on a combination of:

• clinical exam

• hoof and gait assessment

• digital pulse and foot sensitivity

• radiographs when needed

Radiographs are especially important in chronic or uncertain cases because they tell you:

• whether the coffin bone has rotated

• whether sinking is present

• how severe the structural damage is

This changes both prognosis and treatment planning.

What Treatment Usually Involves

Treatment depends on severity, but commonly includes:

• pain relief and anti-inflammatory medication

• soft bedding

• careful movement restriction

• corrective farriery or trimming

• dietary control

• metabolic investigation where indicated

• hoof support such as pads or boots in selected cases

In chronic donkey laminitis, treatment is often not a quick fix. It is a long-term management issue that requires consistency.

Common Mistakes

Assuming donkeys are just stoic or lazy

This is one of the biggest reasons chronic pain gets missed.

Waiting for obvious severe signs

By the time the signs are dramatic, hoof damage may already be advanced.

Focusing only on pasture

Grass matters, but it is not the whole story in donkeys.

Ignoring footing

Hard surfaces can worsen pain and expose underlying laminitis.

Delaying imaging

Radiographs are often what show how serious the problem really is.

Prevention That Actually Helps

Good prevention focuses on:

• regular hoof checks

• consistent farriery

• soft, comfortable footing

• controlled diet

• weight and metabolic management

• early investigation of subtle gait change

• testing for PPID where appropriate

The most useful mindset is this: do not wait for donkey laminitis to look dramatic.

Frequently Asked Questions

Do donkeys get laminitis as often as horses?
They can get it very commonly, and many cases are chronic and recurrent.

Is laminitis in donkeys always caused by rich grass?
No. Pasture can be a factor, but donkey cases do not always follow the classic horse pattern.

Why is laminitis harder to spot in donkeys?
Because they often show pain more subtly and may develop chronic signs gradually.

Should I worry if my donkey is only stiff on hard ground?
Yes. That can be an early sign of foot pain and should not be ignored.

Can chronic laminitis in donkeys be managed?
Often yes, but success depends on catching it early and sticking to a long-term plan.

Final Thoughts

Laminitis in donkeys is common, important, and often underestimated.

The key questions are:

• is the donkey moving normally

• are the hooves changing shape

• is stiffness being dismissed as age or temperament

• could there be a metabolic problem underneath it

These are the questions that prevent chronic pain from being missed.
