Rabbits & small mammals
A head tilt may indicate middle-ear disease or neurologic illness and should be assessed promptly.
SYMPTOM → WHAT DO I DO?
Ear problems
Look for head shaking, odor, discharge, pain and changes in balance.

READ THIS FIRST
Observations can help your veterinarian. They cannot rule out an emergency.
Contact an emergency veterinary facility immediately for difficult breathing, collapse, ongoing seizures, inability to urinate, major bleeding, abnormal gum color, sudden severe abdominal swelling or rapidly worsening weakness.
What could be behind this symptom?
These are possibilities, not a diagnosis. The right explanation depends on the examination, species and medical history.
- Yeast or bacterial ear infection
- Ear mites, foreign material or allergies
- Inflammation, a ruptured eardrum or a deeper ear infection
- Aural hematoma or neurologic disease affecting balance
Ear odor, discharge, and head shaking are observations rather than a diagnosis of bacteria or yeast. Pain can make a proper examination difficult, and the eardrum's condition affects which products are safe. Sampling often helps guide treatment. Recurrent ear disease may reflect an underlying skin or structural problem rather than a need for stronger drops. Bring the names of previous cleaners and medicines and avoid deep cotton swabs or reused prescriptions until the current ear has been assessed.
Inflammation is the body's response to irritation or injury. It can produce swelling, discomfort, and changes in how an organ works, but the word does not identify the cause. Infection, immune activity, trauma, and other processes can all cause inflammation. This distinction matters because an antibiotic treats susceptible bacteria, while inflammation caused by a different process needs a different plan. A temporary improvement in redness or discomfort does not, by itself, establish which cause was present.
An infectious illness depends on both the organism and the animal's ability to resist it. Exposure does not always produce the same severity of illness in every animal. Age, previous immunity, nutrition, stress, and concurrent disease can influence the outcome. The infection may also cause complications that need treatment separately from the organism itself. For example, correcting fluid loss or supporting breathing can be essential even when a targeted medicine has already been started.
A neurologic examination helps locate where a problem may be occurring, such as the brain, spinal cord, peripheral nerves, or balance system. The location then guides the choice of tests. Weakness caused by low blood sugar or another body-wide problem can resemble a primary neurologic disorder, so blood testing may be important even when movement is the main concern. Imaging can provide structural information, but it is selected in the context of the examination rather than ordered identically for every animal.
What can you safely check at home?
Write down what you see and bring photographs or video only when doing so does not delay care.
- Which ear is affected and whether there is odor, wax, blood or discharge
- Head shaking, scratching, head tilt or reluctance to be touched
- Loss of balance, eye flicking or facial changes
- Recent swimming, grooming, allergies or recurrent infections
The most useful home observations compare an animal with its own usual pattern. Record intake, output, weight where practical, activity, and comfortable function at consistent times. Normal variations differ between species and life stages. A brief record can reveal a trend that is difficult to remember accurately or reproduce during an appointment. It also helps assess treatment response. Sudden serious changes still need immediate advice; collecting a perfect record should never delay care.
Avoid actions that can make things worse.
- Do not put peroxide, alcohol, oils or cotton swabs deep in the ear.
- Do not use old prescription drops when the eardrum has not been examined.
- Do not clean a severely painful ear aggressively.
- Do not treat one species with medication labeled for another.
When should you contact your veterinarian?
- Call for redness, odor, repeated shaking, discharge or recurrent ear symptoms.
- Mention previous infections, allergies and any treatment already used.
- Ask whether an examination and ear cytology are needed before medication.
A care plan is easier to follow when expected changes are concrete. Ask which signs should improve, what ordinary functions should return, and how soon the team wants an update if that does not happen. Some problems need repeat measurements or examination even when the animal looks better. Record changes consistently and report new signs separately. A recheck evaluates response, complications, and treatment safety, rather than simply deciding whether to repeat the original prescription.
Get emergency help immediately if you see:
- Sudden severe head tilt, inability to stand or rapid involuntary eye movements
- A rapidly swollen ear flap, uncontrolled bleeding or severe trauma
- Ear signs combined with collapse, neurologic changes or significant pain
The same symptom can mean different things in different animals.
Cats
Ear mites are one possibility, but dark debris can also accompany infection; treatment should follow examination.
