Llama Head Tilt: Ear Disease, Stroke-Like Signs or Neurologic Illness?

A llama with one ear held lower than the other often has vestibular disease, meaning the balance system in the inner ear or brainstem is affected. In camelids, one of the most common practical differentials is otitis media or otitis interna. These ear problems can cause head tilt, loss of balance, nystagmus, facial nerve weakness, ear pain, and reduced appetite. Ear disease may start in the external ear, travel through the eardrum, or spread from the upper airway through the auditory tube.

Another important cause is listeriosis, sometimes called “circling disease.” This bacterial infection can inflame the brainstem and damage cranial nerves, leading to head tilt, circling, facial paralysis, drooling, depression, and recumbency. It is seen most often in ruminants and camelids after exposure to poor-quality or spoiled silage, but it can occur in other feeding situations too.

Less common but serious causes include head trauma, brain inflammation, abscesses, and other central nervous system disease. Camelids can also develop severe neurologic disease from meningeal worm migration, although that more often causes asymmetric weakness and ataxia than an isolated head tilt. Because several of these problems can look similar early on, a head tilt should be treated as a medical urgency rather than watched casually at home.

See your vet immediately if your llama has a new head tilt, especially if it came on suddenly or is paired with circling, stumbling, falling, eye flicking, facial droop, drooling, trouble chewing or swallowing, fever, weakness, or lying down and not wanting to rise. These signs raise concern for inner ear disease, brainstem disease, or a rapidly progressing infection. A llama that cannot eat or drink normally can decline fast.

Even if your llama is still standing and alert, a head tilt is not a symptom to monitor for several days without guidance. Camelids often hide illness until they are significantly affected. Early treatment matters most when infection or inflammation is involved.

While you arrange care, move your llama to a quiet, well-bedded, low-stress area with secure footing and easy access to water and hay. Keep herd mates nearby if that reduces stress, but prevent bullying. Do not force oral medications or large amounts of feed into a llama that seems weak, choking, or unable to swallow normally, because aspiration is a real risk.

Your vet will start with a full physical and neurologic exam. They will look for whether the problem seems more like peripheral vestibular disease from the ear or central vestibular disease involving the brainstem. Helpful clues include nystagmus, facial nerve deficits, fever, mentation changes, ability to stand, and whether your llama is circling or showing other cranial nerve abnormalities.

Depending on the findings, your vet may recommend ear examination, bloodwork, and treatment started the same day if infection is strongly suspected. In some cases, they may collect samples, evaluate for concurrent respiratory or systemic disease, and discuss feed history, including any exposure to spoiled silage or moldy feed.

If the case is severe, not improving, or strongly suspicious for central nervous system disease, your vet may refer for hospitalization, skull imaging such as CT or MRI, and cerebrospinal fluid testing. These tests can help separate ear infection from listeriosis, inflammatory brain disease, trauma, or other neurologic conditions. Supportive care may include fluids, anti-inflammatory medication chosen by your vet, nursing care, and assisted feeding plans if swallowing is safe.

Home care should support your llama while your vet directs treatment, not replace veterinary care. Keep your llama in a dry, deeply bedded pen with non-slip footing and easy access to hay and water at head level that feels natural and safe. Reduce the need to walk long distances. Watch closely for bullying by herd mates, because a dizzy llama may be pushed away from feed.

Monitor appetite, water intake, manure output, temperature if your vet advises it, ability to stand, and any change in eye position or facial symmetry. If your llama is drooling, coughing while eating, or seems unable to chew and swallow normally, contact your vet right away. Those signs can mean cranial nerve involvement and a higher risk of aspiration.

Do not put over-the-counter ear products, oils, or leftover antibiotics into the ear unless your vet specifically tells you to. In food-producing species and camelids, medication choices and withdrawal considerations matter. If your llama becomes more depressed, starts circling, goes down, or stops eating, that is an emergency recheck situation.
