Why Is My Horse Lame?

Common causes of lameness, and when it needs a vet

Quick Answer

Lameness is a sign, not a diagnosis — it can be linked to anything from a hoof abscess to a tendon injury
Sudden, severe, or non-weight-bearing lameness needs prompt veterinary attention
Mild lameness that doesn’t improve with rest still warrants a vet check
Where in the leg the lameness sits, and how it came on, both help your vet narrow down the cause

Common Causes of Lameness

01 Hoof abscess Common

A pocket of infection inside the hoof can cause sudden, often severe lameness in a single leg. It’s one of the most common causes of acute lameness in horses.

02 Bruised sole or foreign body

Stepping on a stone, or bruising from hard or uneven ground, can be linked to localised foot pain that may come on suddenly.

03 Tendon or ligament strain

Overexertion, an awkward step, or work on poor footing can be linked to swelling, heat, and lameness affecting the lower leg.

04 Joint disease or arthritis

Wear on the joints, sometimes age-related, can cause a gradual, often stiffness-led lameness that may improve slightly once the horse is warmed up.

05 Laminitis

Inflammation of the laminae inside the hoof can be linked to lameness affecting more than one foot, often with a reluctance to move and a shifted stance. See our dedicated laminitis guide for more detail.

06 Fracture Emergency

A fracture can be linked to severe trauma, a fall, or a kick, and typically causes an inability or unwillingness to bear weight on the affected leg.

Suspected fractures need emergency veterinary attention — keep your horse as still and calm as possible until help arrives.

Sudden vs Gradual Onset

Sudden Onset

Often linked to an abscess, bruising, a foreign body, or an acute injury. Usually affects one leg and can be quite severe.

Gradual Onset

Often linked to joint disease, low-grade strain, or laminitis. May affect more than one leg and can fluctuate with work or rest.

Contact Your Vet Immediately

Unable or unwilling to put any weight on the affected leg
Visible deformity, wound, or wobbling of the limb
Lameness following a known fall, kick, or road traffic incident
Heat and a bounding pulse in more than one foot, alongside reluctance to move

Don’t move a horse with a suspected fracture more than necessary — call your vet for guidance first.

When to Contact Your Vet

Lameness that doesn’t improve after a short period of rest
Mild lameness that keeps recurring
Any swelling, heat, or sensitivity in the leg or foot
Lameness affecting more than one leg

How Pet Med Direct Can Help

Once your vet has identified the cause of lameness, ongoing support may include joint care products, wound care supplies, or other items recommended as part of your horse’s recovery plan.

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 I work my horse if it’s lame?

It’s best to rest a lame horse and seek veterinary advice before resuming work. Continuing to ride or work a lame horse can make the underlying problem worse.

How can I tell which leg is affected?

A horse will often nod its head down as the sound leg lands, and lift it as the lame leg takes weight. This can be subtle, so your vet may use trotting up in a straight line to help assess it.

Does shoeing affect lameness?

Poorly fitting shoes, overdue trims, or a recent shoeing change can sometimes be linked to lameness. Mention any recent farrier work to your vet.

Is lameness always linked to the leg itself?

Not always — pain elsewhere, such as in the back or neck, can sometimes show up as an irregular gait that looks like leg lameness. Your vet can help work out where the problem is coming from.
