Sheep Stiffness: Causes, Joint Pain, Injury & Neurologic Problems

Stiffness in sheep often starts with pain in the feet or joints. Footrot is a major cause of lameness in sheep, especially in warm, wet conditions. Sheep may walk gingerly, stand hunched, spend more time lying down, and develop a foul odor or separation of the hoof horn. In chronic cases, the hoof can become distorted and more than one foot may be affected.

Joint disease is another important cause. Lambs can develop septic arthritis from bloodstream infection, sometimes called navel ill, or after wounds and contamination. Growing lambs can also develop nonsuppurative polyarthritis caused by Erysipelothrix rhusiopathiae, which often causes sudden moderate to severe lameness in multiple lambs, especially in the carpi and hocks. These lambs may be reluctant to move, spend long periods recumbent, and have enlarged painful joints.

Muscle and nutrition problems can also make a sheep look stiff. White muscle disease from selenium and/or vitamin E deficiency can cause weakness, stiffness, and difficulty rising, especially in young, fast-growing lambs. Trauma, sprains, fractures, hoof abscesses, and toxin exposures can also cause a stiff gait. In some pasture-related toxicoses, sheep may show a high-stepping or rocking-horse gait.

Not all stiffness is orthopedic. Neurologic disease can mimic lameness. Sheep with listeriosis, scrapie, lead poisoning, tetany, or other nervous system disorders may appear weak, uncoordinated, or stiff rather than truly lame. If you notice circling, head tilt, blindness, tremors, exaggerated reactions, or repeated falling, your vet will need to sort out whether the problem is pain, muscle disease, or the nervous system.

See your vet immediately if the sheep cannot stand, is non-weight-bearing, has severe or constant pain, has a suspected fracture or deep wound, or is showing neurologic signs such as circling, seizures, tremors, collapse, blindness, or head pressing. Fast care also matters if a lamb is weak and stiff, if several sheep become lame at once, or if there is fever, rapid breathing, or sudden swelling of one or more joints.

Same-day or next-day care is wise for stiffness lasting more than 24 hours, visible hoof damage, foul-smelling feet, swollen joints, reduced appetite, weight loss, or reluctance to walk to feed and water. Sheep often hide pain, so a mildly stiff gait can still reflect a meaningful problem.

Short monitoring at home may be reasonable only if the stiffness is mild, the sheep is still eating, walking, and bearing weight, and you can link it to a brief strain or minor footing issue. During that time, move the sheep to a dry, well-bedded area with easy access to feed and water, and watch closely for worsening. If there is no clear improvement within a day, or if anything about the gait looks neurologic rather than painful, contact your vet.

Your vet will start by deciding whether the stiffness is coming from the feet, joints, muscles, or nervous system. That usually means watching the sheep walk, feeling the limbs and spine, checking hoof health, testing joint range of motion, and looking for heat, swelling, wounds, or asymmetry. A neurologic exam may be needed if the gait is weak, wobbly, or abnormal in more than one limb.

Diagnostics depend on the likely cause. For foot disease, your vet may trim and examine the hoof closely. For joint disease, they may recommend bloodwork, joint fluid sampling, or imaging. Radiographs can help with fractures, chronic joint damage, or severe foot problems. In lambs, your vet may also consider navel infection, selenium status, or infectious causes affecting multiple animals.

Treatment is tailored to the cause and the flock situation. Options may include hoof trimming, footbaths, bandaging, anti-inflammatory medication, antibiotics when infection is suspected, mineral correction, fluid support, or humane euthanasia in severe nonrecoverable cases. Your vet will also discuss isolation, footing, bedding, nutrition, and whether other sheep in the group need to be examined.

While you are waiting for your appointment, keep the sheep in a dry, deeply bedded, non-slip area with easy access to hay and clean water. Limit walking distance and avoid forcing movement, especially if the sheep is painful or wobbly. If flock pressure is a problem, house the sheep with one calm companion or where it can still see the group.

Check the feet and lower legs only if it is safe to do so. Look for mud packing, foul odor, overgrown horn, wounds, heat, or obvious swelling. Do not aggressively trim hooves, lance swellings, or pull at loose horn unless your vet has shown you how. If the sheep is down, turn it regularly, keep bedding clean and dry, and make sure it can reach feed and water without struggling.

Do not give over-the-counter human pain relievers or leftover livestock drugs without veterinary guidance. Sheep need species-appropriate dosing, and food-animal withdrawal rules matter. If your vet prescribes treatment, give every dose exactly as directed and recheck promptly if the sheep is not improving within 24 to 48 hours.

Longer term, prevention often matters as much as treatment. Good hoof care, dry footing, clean lambing and processing practices, balanced mineral nutrition, and quick attention to wounds can reduce future stiffness problems. If more than one sheep is affected, tell your vet right away because flock-level disease control may be needed.
