My dog's ear is swollen, itchy, and waxy. Is it an infection?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Male | neutered | 9 years old

For the past few days, my dog has been tilting his head and violently scratching his left ear. When I went to check it out, the ear was swollen and full of flaky yellow wax. The other ear seems perfectly normal with no issues. I don't know what to do.

Poor Bowey, it sounds like that ear is really uncomfortable! I would recommend a visit to your vet. They will do a thorough exam, and likely take some samples of the debris is Bowdy's ear to look at under the microscope. This will help determine if an infection is present, and what type of medication is most effective. Ear infections can be cause by yeast, or bacteria, sometimes both. Your vet will likely prescribe an ear cleaning solution and a medicated ointment or drops for Bowdy's ear. If the flap of the ear is swollen Bowdy may be dealing with an ear hematoma as well-this is when there is a collection of blood/fluid under the skin of the ear flap. It sometimes happens secondary to an ear infection when they are shaking and scratching a lot. Sometimes they need to be surgically drained, other times can be treated medically. I hope Bowdy feels better soon!

    Poor Bowdy! From your description and picture, it looks like he has an ear infection. I would recommend that you take him to see you veterinarian. Ear infections can be quite uncomfortable and can lead to other complications such as hematomas in the ear flap if left untreated. Your veterinarian will perform a thorough examination and will likely take a sample from Bowdy's ear to determine what type of infection is present. This will allow them to choose the best treatment protocol. Please do not use any over the counter ear cleaners or other products in the ears as many contain alcohol or weak acids that can be painful when applied to an inflammed ear.
