Overview
If your dog’s ear is wet inside all the time, the most common reason is trapped moisture, wax, or discharge. It can also happen with irritation, a build-up of debris, or an ear problem such as an infection. You can check for a few simple signs at home, but if the ear stays damp or there’s smell, redness or your dog seems uncomfortable, it’s worth getting veterinary advice.
Things To Check
1. See whether the ear is wet after swimming, bathing, rain, exercise or a walk in long grass.
2. Look for smell, redness, swelling, discharge, scabs or any visible soreness around the ear.
3. Check whether your dog is shaking their head, scratching at the ear or tilting their head more than usual.
4. Notice if the wetness is clear moisture, waxy residue, or thicker discharge that looks yellow, brown or creamy.
5. Compare both ears, as one ear being wetter than the other can be a useful clue.
6. Think about whether your dog has floppy ears, a lot of hair in the ear, or a history of ear problems, as these can make moisture linger.
7. Check whether grooming, ear cleaning or washing may have left water or product trapped in the ear.
Common Causes
Trapped water is a common reason, especially after bathing, swimming or wet weather. Ear wax and normal skin oils can also make the inside of the ear feel damp.
Otitis externa, which is inflammation of the ear canal, is another common cause. This may be linked with yeast, bacteria, allergies or irritation and often comes with smell, redness or scratching.
Less commonly, a foreign body such as grass seed, ear mites or a small wound inside the ear can cause ongoing wetness or discharge. In some dogs, deeper ear problems can also play a part.
What To Do
Gently dry only the outer part of the ear if it’s wet after swimming or washing. Do not push cotton buds or anything else into the ear canal.
Keep a note of when the wetness happens, what it looks like and whether there’s any smell or behaviour change. That can help you spot a pattern.
If your dog is prone to damp ears, keep grooming and washing routines calm and careful, and avoid letting water collect in the ear. If the ear seems sore, don’t try to clean deeply at home.
When To Contact A Vet
Speak to your vet if the ear stays wet for more than a day or two, smells unpleasant, looks red or swollen, or your dog is scratching, head-shaking or seems painful. Get advice sooner if there is discharge, a head tilt, balance problems or your dog seems unwell.
Products That May Help
For dogs with ears that get damp easily, a gentle grooming and hygiene routine can help you stay on top of day-to-day care. The Pet Care collection may be useful as part of that routine.
