If your dog’s ears smell different after swimming, treat the change as information. Water can remain in or around the ear after a lake day, creek run, pool session, or bath. A noticeable odor does not diagnose an infection, but odor combined with head shaking, scratching, redness, discharge, swelling, or pain is a reason to call your veterinarian.
Quick answer: What should I do when my dog’s ears smell after swimming?
Dry the outer ear flap and surrounding coat with a clean towel. Look without pushing into the canal. Do not use cotton swabs, household mixtures, K9 skin products, or an unfamiliar ear cleaner. Call your veterinarian when the smell is strong, continues after the dog is dry, or appears with redness, discharge, pain, repeated head shaking, scratching, swelling, a head tilt, or balance changes.
Why can a dog’s ears smell after swimming?
A dog’s ear canal does not drain like a straight tube. Moisture can remain after swimming, especially in dogs with drop ears, thick hair around the ears, allergies, or a history of recurring ear concerns. Cornell University College of Veterinary Medicine explains that a warm, moist ear canal can create conditions where yeast and bacteria grow more readily. Review Cornell’s itchy-ear guidance.
Smell alone cannot tell an owner whether the cause is trapped moisture, wax, irritation, a foreign object, allergy-related inflammation, yeast, bacteria, or something else. A veterinarian may need to examine the canal and eardrum before recommending what belongs in the ear.
What should owners check before touching the ear?
Source of the odor: Is it coming from the coat, collar, or clearly from one ear?
Head movement: Watch for repeated shaking, a head tilt, or holding one ear differently.
Scratching and rubbing: Notice pawing at the ear or rubbing the head on furniture or the ground.
Visible changes: Check the outer ear for redness, swelling, moisture, increased wax, blood, or discharge.
Comfort: Stop if the dog pulls away, cries, guards the ear, or appears painful.
Whole-dog behavior: Note appetite, energy, walking, and balance.
Compare both ears. A one-sided change can help the veterinarian understand the pattern, but it does not identify the cause at home.
What is a safe post-swim ear routine?
Move to a calm, well-lit area. Let the dog shake naturally before beginning your check.
Dry the outside only. Use a clean, soft towel on the ear flap and the hair around the opening.
Dry the rest of the dog. Pay attention to the collar line, neck, skin folds, paws, belly, and dense coat. Use the wet dog coat check for the full routine.
Look and smell without probing. Do not insert a swab, finger, or tool into the canal.
Follow the dog’s established veterinary plan. If your veterinarian has already recommended a specific post-swim ear cleaner for this dog, use it exactly as directed.
Recheck later. Persistent odor, new discomfort, or increasing signs deserve a veterinary call.
What should never go into a dog’s ear without veterinary guidance?
Do not improvise with alcohol, hydrogen peroxide, vinegar mixtures, essential oils, skin sprays, shampoos, or other household products. Cornell’s ear-cleaning guidance notes that alcohol and hydrogen peroxide can irritate the ear. It also explains that overcleaning can create irritation and that the right cleaner depends on the dog and the condition of the ear. Read Cornell’s dog ear-cleaning guide.
A damaged eardrum or painful canal is not visible to an owner from the outside. That is why a product that seems harmless can be the wrong choice for a particular ear.
When should a veterinarian examine the ear?
Call your veterinarian promptly for a strong or persistent odor, redness, swelling, discharge, blood, marked tenderness, repeated head shaking, repeated scratching, or an ear that suddenly hangs differently.
Seek urgent veterinary help for loss of balance, falling, circling, a pronounced head tilt, severe pain, rapid swelling of the ear flap, unusual eye movements, weakness, or a dog that seems significantly unwell. Do not clean a painful or severely swollen ear before veterinary guidance.
Does K9 by Draw It Out® fit this ear concern?
No K9 by Draw It Out® product belongs in the ear canal, and K9 skin and coat products do not diagnose or address an ear infection. Keep this question veterinary-first. After the ears have been assessed and the rest of the dog simply needs ordinary external coat or post-activity care, use the K9 by Draw It Out® dog-care hub to choose an appropriate routine.
If the swim occurred in suspicious water, treat that as a separate safety question. Review the blue-green algae and dogs safety guide and contact a veterinarian immediately after a suspected harmful-algae exposure.
Dog ears smell after swimming FAQ
Is ear smell after swimming normal?
A damp coat can have a temporary wet-dog smell. A distinct odor from one or both ears, especially when it continues after drying or appears with discomfort, deserves a veterinary call.
Can I clean my dog’s ears after every swim?
Use only the routine and ear cleaner your veterinarian has recommended for that dog. Healthy ears may need post-swim drying or a veterinarian-approved cleaner, but unnecessary cleaning can irritate the canal.
How should I dry my dog’s ears after swimming?
Let the dog shake, then gently towel-dry the outer ear flap and surrounding hair. Do not insert cotton swabs, fingers, or tools into the canal.
When is a smelly dog ear urgent?
Seek urgent veterinary help for balance problems, falling, circling, a pronounced head tilt, severe pain, rapid ear-flap swelling, unusual eye movements, weakness, or a dog that seems significantly unwell.
Can I use a K9 by Draw It Out® product in my dog’s ear?
No. K9 by Draw It Out® skin and coat products are not ear medications and should not be put into the ear canal. Contact your veterinarian for ear-specific guidance.

Absolutely the best way to finish after a hard workout on fresh cattle. My cowhorse actually grins and pops his lips when I spray him down with Draw It Out Icebath after a workout. Then I take a small rubber curry and work it into his coat. As he stands there absorbing the brace I can actually see the muscle tension releasing and relaxing. Wonderful product for hot post workout days.
