Dog ear issues: the warning signs owners should document
Ear problems are one of the most common reasons dogs see the vet, and one of the most common reasons home treatment makes things worse. Knowing what to write down — not what to apply — is the right starting point.

Quick answer: Write down what you see (redness, discharge, smell, head tilt), what you hear (head shaking, scratching at the ear), and when it started. Photograph the ear from outside the canal. Call the vet rather than reaching for human ear drops or hydrogen peroxide.
Why documentation matters
Ear infections in dogs can have very different causes — bacterial, yeast, ear mites, foreign bodies, allergies, anatomy. The treatment depends on the cause. The cause is hard to guess from a written description; the vet usually needs a swab and an exam.
But what owners observe between visits is genuinely useful. The pattern (one ear or both, intermittent or constant, post-swim or year-round) often guides workup.
What to watch for
- Head shaking — more than the casual after-nap shake
- Scratching at one or both ears repeatedly
- Redness inside the ear flap (visible from outside the canal, do not probe)
- Discharge — brown, black, yellow, waxy, or pus-like
- A strong smell that is new
- Head tilt or balance issues — treat as urgent
- Pain when ears are gently touched
- Sudden change in temperament around handling
What not to do at home
Do not put hydrogen peroxide, rubbing alcohol, vinegar, human ear drops, or essential oils in a dog’s ear unless a vet has specifically directed you to. Several over-the-counter human products can damage the ear canal or rupture an eardrum.
Do not use cotton swabs deep in the canal. Surface wiping of the ear flap with a damp cloth is fine; canal cleaning is a vet’s call.
What to write down before the visit
- When did you first notice the change?
- One ear or both?
- Any recent swimming, bathing, ear cleaning, or topical products?
- Any known allergies or chronic skin issues?
- Current diet and any recent diet changes
- Photos of the visible ear (taken in daylight, not flash)
Urgent signs
Head tilt, sudden balance problems, vomiting paired with ear symptoms, or rapid swelling around the ear are vet-now signs, not vet-tomorrow signs. Call your vet or an emergency clinic immediately.
How Driyu fits
Driyu’s pet profile carries known allergies, current medications, and a simple recent-observations field. When you call the vet, the relevant history is in one place — you do not reconstruct it from memory under stress.

Frequently asked questions
Can I clean my dog’s ears at home?
Routine surface cleaning of healthy ears with a vet-approved cleaner is fine. Cleaning an inflamed or painful ear at home can make things worse and obscures the diagnosis. Ask your vet what is appropriate for your dog.
Why does my dog get recurring ear infections?
Recurring infections often have an underlying cause — allergies, anatomy (floppy ears, narrow canals), moisture from swimming, or hormonal imbalance. A vet can investigate the pattern.
Is head shaking always a sign of an ear issue?
Frequent or sudden head shaking often points to ears, but can also signal other conditions. Document the pattern and call your vet.
When is a head tilt an emergency?
A sudden head tilt with balance issues, vomiting, or eye movement changes is urgent. Call your vet or emergency clinic right away.
