What does head shaking / ear scratching mean?
Occasional head shaking in a bright, eating dog is often ear irritation from allergy, water, or infection. A head tilt, a swollen ear flap, bleeding, or a dog who cannot settle needs a same-day exam. Do not put anything into the ear canal.
Occasional head shaking with a bright, eating dog is often ear irritation. A head tilt, bleeding, or a dog who cannot settle needs a same-day exam. This is a triage guide, not a diagnosis for the animal in front of you.
What are common causes?
- Ear mites, yeast, or bacterial irritation
- Allergy flare or water left in the ear after swimming
- A grass seed or other foreign body
- Less often, a middle-ear or neurologic problem
What should I check at home?
Use this checklist once, then stop if handling increases distress or breathing worsens. Breathing rate, gum color, and appetite are the checks that change the plan, and a missed meal is more urgent in a bird or rabbit than the same gap in a dog. Write down what you see, including when the sign started, before you call.
- Confirm they are eating, drinking, and walking normally.
- Look at the ear flap for redness, swelling, or a bad smell. Do not push anything into the canal.
- Check gum color. Pink and moist is reassuring. Pale, blue, or brick-red gums are an emergency.
- Count resting breaths for 15 seconds and multiply by four. A calm dog is often near 15–30 breaths per minute.
When is this an emergency?
- The head is tilted and stays that way, or the dog walks in circles.
- There is blood, a swollen ear flap, or crying when the mouth opens.
- They are lethargic, vomiting, or have pale gums.
- Shaking started after a fight, a fall, or a possible foreign body.
