tear duct issue vs upper respiratory in rabbits

updated 19 May 2026

in Singapore, rabbit owners face a specific challenge that owners in temperate climates largely do not. the combination of 28 to 32°C heat and 70 to 90% humidity year-round creates an environment where respiratory irritants linger, nasal passages stay inflamed, and secondary infections take hold faster. add HDB flat ventilation constraints, and you have a situation where two very different rabbit conditions, blocked tear ducts and upper respiratory infections, can escalate from “minor symptom” to “vet emergency” within days. the catch is that both conditions can look almost identical from the outside. understanding how they differ, and where they overlap, is one of the most useful things you can learn as a SG rabbit owner.

how blocked tear ducts present

rabbits have a nasolacrimal duct, a narrow channel that drains tears from each eye down into the nasal cavity. when this duct becomes blocked, tears have nowhere to go. they overflow the lower eyelid and run down the face instead.

you will see a wet streak below one or both eyes. the fur in that area mats, crusts, and can become sore from constant moisture. the skin underneath may redden or show mild inflammation.

the discharge from a blocked tear duct is usually clear or faintly white. if a secondary bacterial infection has developed in the stagnant fluid, the discharge may thicken and smell slightly.

a key diagnostic clue: a rabbit with a blocked tear duct alone will not sneeze. it will not have a runny nose, a rattling chest, or wet front paws from wiping its face. the problem is confined to the eyes and the fur directly below them. if you see only the eye symptoms without any nasal signs, blocked tear duct is more likely.

how upper respiratory infections present

upper respiratory infections in rabbits, commonly called snuffles, affect the nasal passages, sinuses, and sometimes the upper airway. the hallmark signs are repeated sneezing, not the occasional sneeze, but bouts of several sneezes in a row. nasal discharge follows, starting clear and often turning thick and white or yellow as the infection progresses.

you may hear a snuffly or gurgling quality to the breathing. the rabbit’s front paws may be crusty or damp from wiping its nose repeatedly.

now here is where owners get confused. the nasolacrimal duct connects the eye and nasal passages. when the nasal cavity is inflamed, that shared duct can back up. fluid accumulates and exits through the eye instead. so a rabbit with an active upper respiratory infection may show discharge at both the nose and the eyes simultaneously.

a rabbit with only a blocked tear duct will not have nasal discharge. a rabbit with a URI may have both. this asymmetry is the key to reading the situation before your vet visit.

the pasteurella connection

Pasteurella multocida is the most common bacterial cause of respiratory disease in rabbits. many rabbits carry it in their nasal passages without showing symptoms for months or years. stress, poor diet, dusty bedding, smoke, and environmental irritants can tip a carrier rabbit into active illness.

in SG households, common triggers include temperature swings between outdoor heat and heavily air-conditioned rooms, dusty hay stored in humid conditions, and cigarette or incense smoke drifting in from HDB corridors.

Pasteurella is the primary cause of snuffles. it is also frequently found in tear duct infections. a chronically wet eye area becomes a breeding ground for bacteria, and Pasteurella is often the species that settles there.

this overlap means that even when the main diagnosis is a blocked tear duct, your vet may still find Pasteurella involved. a bacterial culture and sensitivity test on the discharge identifies exactly which antibiotic will work. this matters because Pasteurella strains in Singapore rabbits can vary in their resistance profiles, and using the wrong antibiotic delays recovery.

the dental connection owners miss

this is the part that surprises most owners. the roots of a rabbit’s upper cheek teeth, specifically the premolars and molars, run very close to the path of the nasolacrimal duct. when a rabbit develops dental disease, elongated tooth roots or molar spurs can physically press on that duct and block it.

the result looks like an eye problem. it is actually a dental problem.

treating only the eye will not resolve it. the tear duct will block again and again until the dental issue is addressed. if your rabbit has recurring blocked tear ducts that keep coming back despite treatment, ask your vet about dental X-rays.

not all SG exotic vets have dental X-ray equipment. it is worth asking before you book so you can choose a clinic with the right tools. as of 2026, a dental examination with X-rays at an exotic vet in Singapore typically costs SGD 150 to SGD 400, depending on whether sedation is needed and the complexity of the case.

if molar spurs or elongated roots are confirmed, a procedure under sedation may be required to file them down. older rabbits carry a higher anaesthetic risk, so catching dental disease early makes treatment safer and outcomes better.

what a SG vet visit looks like

a proper workup for either condition starts with a physical exam: the eyes, nasal passages, face, and lymph nodes under the jaw. the vet may flush the nasolacrimal duct with saline to check whether it is open. discharge may be collected for bacterial culture.

if dental disease is suspected, X-rays or CT imaging may be recommended. CT gives more accurate views of tooth roots but is not available at every SG exotic clinic. as of 2026, a CT scan for a rabbit can cost SGD 600 to SGD 1,200 or more depending on the facility and complexity.

a standard exotic vet consultation in Singapore typically runs SGD 60 to SGD 120 before diagnostics or medications. always specify that you are bringing a rabbit and ask whether the clinic sees exotic animals regularly. a general cat and dog clinic may not have the handling experience or diagnostic tools needed for accurate rabbit assessment.

what owners often get wrong

treating the eye without a diagnosis. buying eye drops at a pet shop or requesting antibiotic eye drops without identifying the cause is the most common mistake. if the real issue is dental disease or systemic Pasteurella, eye drops will not fix it. the problem recurs, sometimes with complications.

waiting because the rabbit is still eating. rabbits are prey animals hardwired to hide illness. a rabbit with a URI or blocked tear duct may eat, groom, and appear alert right up until the condition worsens significantly. do not interpret normal appetite as a sign that the situation is not serious.

blaming the humidity and waiting it out. SG’s climate does affect airways, but persistent eye discharge, repeated sneezing, or facial wetness lasting more than two to three days is not normal weather-related irritation. it needs a vet assessment, not another week of monitoring.

stopping antibiotics before the course ends. Pasteurella is stubborn. some rabbits become lifelong carriers, and managing it requires completing the full antibiotic course your vet prescribes. stopping early because symptoms improved is a common reason for relapse and contributes to antibiotic resistance developing in your rabbit’s bacterial population.
