Frequency and context matter more than one shake
Note whether shaking began after swimming, grooming, a walk through tall grass or use of a new ear product. Watch for scratching, rubbing the face, holding one ear lower, crying when chewing, avoiding touch or losing balance. A short video can show the motion and head position without making you restrain the dog.
What you can safely see
In good light, compare the visible ear flaps and the entrance to each canal. Look for redness, swelling, discharge, excess debris, odor or a foreign object at the very opening. Do not insert cotton swabs, tweezers or a camera. A grass awn or other object may sit deeper than you can see, and a damaged eardrum changes which products are safe.
- Start time and whether one or both ears seem involved
- Swimming, bathing, grooming or field exposure
- Scratching, odor, discharge or pain
- Head tilt, circling, stumbling or unusual eye movement
- Previous ear problems and current products
- Whether the ear flap is becoming thick or swollen
Why leftover ear drops are a bad test
Different ear problems can look alike. Medication that helped last time may be wrong for the current organism, unsafe with an injured eardrum or expired. Cleaning a painful ear before the appointment can also remove material the clinic needs to examine. Unless your veterinarian has given a standing plan for this dog, leave the canal alone.
Call promptly for these changes
Arrange care for repeated shaking or scratching, odor, discharge or obvious discomfort. Same day assessment is sensible for a suddenly swollen ear flap, marked pain, bleeding or a suspected foreign object. A persistent head tilt, loss of balance, falling, circling, rapid eye movements, facial weakness or vomiting can indicate deeper ear or neurologic involvement and needs urgent evaluation.
This article owns repeated head shaking. General fishy odor maps to the odor guide, while cloudy eyes, eye discharge and facial squinting belong to their eye specific destinations.
Until the appointment, keep the ear dry and prevent rough play that triggers more violent shaking. A soft recovery collar may sometimes reduce self injury, but fit and suitability should be discussed with the clinic, especially for a dog who panics in equipment. Check the ear flap several times for new balloon like swelling because repeated impact can allow blood to collect within it. If the dog has a history of allergies or recurring ear disease, bring the names and dates of previous products rather than assuming this episode is the same. The clinic may need material from the ear before cleaning in order to choose an appropriate plan.
