Laminitis in Horses

Early signs, common causes, and when it’s an emergency

Quick Answer

Laminitis is inflammation of the sensitive laminae inside the hoof, and can affect one or more feet
Early signs include reluctance to move, a shifted “rocked back” stance, and heat in the hooves
Certain horses and ponies, particularly those that are overweight or have an underlying endocrine condition, are at higher risk
Any suspected laminitis needs prompt veterinary attention — delays can worsen the outcome

Early Signs of Laminitis

Reluctance to walk, turn, or move off
Shifting weight from foot to foot, or rocking back onto the heels
A short, stilted, or “walking on eggshells” gait, especially on hard ground
Heat in one or more hooves
A stronger than normal digital pulse felt at the back of the fetlock
Lying down more than usual, or reluctance to get up

Common Causes

01 Excess weight or rich grass Diet-related

Sudden access to lush spring or autumn grass, or carrying excess weight, can be linked to a higher laminitis risk, particularly in ponies and native breeds.

02 Underlying endocrine conditions Common in older horses

Conditions such as equine metabolic syndrome or PPID (Cushing’s) are commonly linked to recurring laminitis episodes, especially in middle-aged and older horses.

03 Mechanical overload

If a horse is bearing extra weight on one leg, for example due to an injury on the opposite limb, this can be linked to laminitis developing in the overloaded foot.

04 Severe illness

Certain serious systemic illnesses can be linked to laminitis developing as a secondary complication.

Contact Your Vet Immediately

Sudden, severe reluctance or refusal to move
Lying down and unwilling to get up
Strong, bounding digital pulses in more than one foot
Visible changes to the angle or shape of the hoof

Early veterinary treatment gives the best chance of limiting long-term damage inside the hoof.

When to Contact Your Vet

Any first suspected episode of laminitis, even if signs seem mild
A horse or pony with a known history of laminitis showing early warning signs again
Ongoing weight gain or a known endocrine condition alongside any change in gait

How Pet Med Direct Can Help

Once your vet has assessed your horse, ongoing management may include weight and diet control, restricted grazing, and pain relief or other treatment as prescribed.

Pet Med Direct stocks a range of equine weight management and wellbeing products to support your vet’s recommendations.

Some treatments require a valid veterinary prescription. Pet Med Direct can only supply prescription medicines after the prescription has been checked. Always follow your vet’s advice and the directions on the medicine label.

Frequently Asked Questions

Can laminitis happen in winter?

Yes — although it’s often associated with spring grass, laminitis can develop at any time of year, particularly in horses with an underlying endocrine condition.

Does laminitis only affect overweight horses?

No. While excess weight is a recognised risk factor, laminitis can also affect horses at a healthy weight, especially where an underlying illness or endocrine condition is involved.

Can laminitis come back after recovery?

Yes, recurrence is common, particularly if an underlying cause such as an endocrine condition isn’t being managed. Ongoing monitoring with your vet is important for at-risk horses.

Should I restrict grazing if I suspect laminitis?

Speak to your vet promptly rather than waiting — they can advise on safe management of turnout and diet alongside any treatment needed.
