Goat Nasal Discharge: Causes of Runny Nose, Mucus or Pus

Nasal discharge in goats is a symptom, not a diagnosis. The color, thickness, smell, and whether it comes from one nostril or both can help your vet narrow the cause. Clear or watery discharge may be seen with dust, hay irritation, transport stress, or early viral respiratory disease. As inflammation worsens or secondary bacteria move in, the discharge can become thicker and more mucoid or mucopurulent.

In goats, respiratory disease is a common reason for a runny nose. Merck notes that upper airway problems in sheep and goats include sinusitis, nasal foreign bodies, nasal tumors, and pharyngeal-laryngeal disorders, while lower airway disease includes viral, bacterial, and parasitic pneumonia. Bacterial bronchopneumonia and pasteurellosis are important causes, especially after stress, crowding, weather swings, poor ventilation, or a preceding viral infection. Mycoplasma infections can also cause fever, cough, fast breathing, and nasal discharge.

A one-sided discharge raises concern for a local problem inside the nose or sinus, such as a grass awn, feed material, tooth-root disease extending into the sinus, an abscess, or a mass. Merck also describes enzootic nasal tumors in goats, which can cause serous, mucoid, or mucopurulent discharge, reduced airflow, sneezing, head shaking, and progressive breathing difficulty.

Parasites are another possibility in some regions and management systems. The sheep nasal bot can affect goats as well and may cause sneezing, head shaking, and nasal discharge. Less often, facial skin disease around the nostrils, including contagious ecthyma (orf), can create crusting and secondary discharge that pet parents mistake for a simple runny nose.

A small amount of clear discharge in an otherwise bright, eating goat may be reasonable to monitor for 12-24 hours if there is an obvious irritant, such as dusty bedding or hay, and breathing remains normal. During that time, watch appetite, cud chewing, rectal temperature if you know how to take it safely, breathing rate and effort, and whether the discharge changes from clear to cloudy or thick.

See your vet the same day if the discharge is thick, pus-like, foul-smelling, bloody, or coming from only one nostril. You should also call promptly if your goat has fever, cough, noisy breathing, open-mouth breathing, stretching the neck to breathe, reduced milk production, poor appetite, depression, or dehydration. Kids, seniors, pregnant does, and goats with known chronic disease deserve a lower threshold for an exam.

See your vet immediately if your goat is struggling to breathe, cannot keep up with the herd, will not eat or drink, has blue or gray gums, collapses, or has severe facial swelling. Respiratory disease in goats can move from mild upper airway signs to pneumonia or systemic illness quickly, and early treatment often gives your vet more options.

Your vet will start with a full history and physical exam. Expect questions about how long the discharge has been present, whether it is one-sided or both-sided, recent transport or weather stress, new herd additions, coughing, appetite changes, and whether other goats are affected. Your vet will listen to the lungs, check airflow from each nostril, look for oral lesions or dental problems, and assess temperature, hydration, and breathing effort.

Depending on the findings, your vet may recommend a stepwise workup. This can include nasal swabs, culture or PCR testing, bloodwork, fecal testing for lungworm or other parasites, and imaging such as skull or chest radiographs. In herd cases, your vet may also discuss group-level diagnostics and biosecurity. Merck notes that diagnosis of respiratory disease in small ruminants may involve culture, PCR, and fecal Baermann testing when lungworm is a concern.

If your vet suspects a deeper nasal problem, they may recommend sedation for a more complete oral and nasal exam, flushing, endoscopy where available, or referral imaging. Treatment depends on the cause and may include anti-inflammatory care, antimicrobials selected by your vet, parasite treatment, drainage of abscesses, oxygen support, fluids, or more intensive care for pneumonia. Isolation from herd mates may be advised while contagious causes are being considered.

Home care should support breathing and reduce irritation while you stay in contact with your vet. Move the goat to a clean, dry, well-ventilated area away from dust, moldy hay, and ammonia buildup. Offer easy access to fresh water and normal feed, and watch closely for reduced appetite, fewer rumen movements, or separation from the herd. If other goats are showing signs, mention that to your vet right away.

Gently wipe away discharge from the nostrils with a soft damp cloth if your goat tolerates it. Do not force anything into the nostrils, and do not try home flushing, essential oils, or over-the-counter cold medicines. These can delay diagnosis or make breathing worse. If your vet has prescribed medications, give them exactly as directed and ask about meat and milk withdrawal times for any drug used in goats.

Keep a simple log of temperature, appetite, breathing effort, cough, and discharge color once or twice daily. That record can help your vet decide whether the current plan is working. If the discharge becomes thick, bloody, foul-smelling, one-sided, or your goat starts breathing harder, stop monitoring and contact your vet promptly.
