Why does my dog keep shaking her head after walks, and when should ears be examined?

Published October 25, 2026

The short answer

A few shakes after a walk can simply clear water or loose debris, but repeated shaking points to irritation inside her ear, and vets consider grass seeds or awns, trapped water and ear mites among the possibilities to check. Book an examination if the shaking persists, or if you notice smell, discharge, redness or pain when her ear is touched. Never clean a red, painful or smelly ear at home; a drying cleaner belongs in her routine only if the vet recommends one. With KinsLe's Pet Passport, you can keep dated walk and ear notes with her visit record for the appointment.

One or two full shakes on the doorstep are ordinary dog maintenance, the same shake that sends water flying after a bath. The pattern worth attention is different: shaking that starts on the walk and keeps returning at home, shaking aimed at one side, or shaking paired with scratching at an ear or a new reluctance to have that ear touched. Walks expose her ears to the outdoors in a way the house does not. Long grass brushes her head at ear height, puddles and wet verges splash upward, and her ear flap, especially on breeds with heavy hanging ears, traps whatever arrives against a warm, narrow canal. When shaking follows walks again and again, the walk itself is part of the evidence, and the ear deserves a proper look rather than another wipe.

What a Walk Can Leave in Her Ears

Grass seeds and awns lead the list of possibilities a vet will check after walks in grassy places, because their barbed shape works inward with movement and a seed lodged in the canal causes exactly this picture of sudden, repeated shaking, often starting during or just after the walk. Water is the simpler candidate: rain, puddle splashing or a swim can leave moisture deep in the canal, and she shakes to clear it, which works when the ear is healthy and the water is only water. Ear mites are a further possibility the vet considers, particularly in younger dogs, and they cannot be confirmed by looking at the ear flap at home. Each of these is a possibility for the vet to investigate with an examination, often using a scope to see the full canal, not a verdict an owner can reach from the doorway, which is why persistent shaking earns an appointment rather than a home experiment.

The Signs That Mean Examine, Not Clean

Book the examination when shaking persists beyond the evening of the walk, returns daily, or centres on one ear. Smell is a trigger on its own: a sour or yeasty odour from the ear that was not there before means the ear needs examining, not cleaning. Discharge, whether dark and waxy, yellow or bloody, redness inside the flap, swelling, or pain when the ear is touched all belong in the same category. A head tilt, scratching that breaks the skin, or a dog who cries out when her collar passes over the ear should be seen promptly. The cleaning rule follows from this: an ear that is red, sore or smelly should not be cleaned at home, because fluid pushed into an irritated canal can reach places it should not if the eardrum is damaged, and cleaning first can also blur what the vet needs to see. A drying cleaner has a place after swimming or bathing for some dogs, but only if the vet recommends one for her ears specifically; it is not a treatment for an ear that already hurts, smells or discharges.

What to Tell the Vet

Details from the walks sharpen the examination. Say where she walks, whether the route runs through long grass, when the shaking started and whether it favours one ear. A walk and ear note that carries this well holds exactly four fields, date, walk route, shaking pattern, ear appearance, and a real entry might read: date, Saturday 10 May; walk route, riverside path with long grass along the bank; shaking pattern, repeated shakes for an hour after arriving home, mostly toward the right; ear appearance, right ear red at the opening with a sour smell. An entry like that tells the vet where to look first and why. Avoid putting anything into the ear before the visit unless the clinic advises it when you phone, and stop her scratching at the skin if you can do so calmly, since broken skin adds a second problem beside the ear itself. Keeping that note in your Pet Passport means her walk routes and ear history arrive at the appointment with her, stored inside KinsLe and ready for the vet to work from.
