What causes a dog's red, oozing ear with thick discharge and head shaking?

Updated On September 23rd, 2025

Pet's info: Dog | Great Dane | Male | neutered | 115 lbs

My dog has thick back stuff only in one ear. He’s been shaking his head lots and now it’s very red and kind of oozing. When I clean it he’s not bothered like it hurts. It doesn’t have an odor. He’s a 5yr old Great Dane. Ears are not cropped. The pics are after cleaning The gunk out

Poor Jersey's ear looks red and inflamed! His symptoms are indicative of an ear infection, and he will need to see a vet as soon as possible for it. Ear infections can be caused by bacteria, yeast, or ear mites, so the vet will need to confirm he does have an ear infection, what is causing it, and then can prescribe the correct treatment for him. It's very important to have him seen as soon as you can because leaving this untreated can lead to hearing loss. Good luck, I hope this helps!

My 12yr old boxer/terrier mix has moderate amount of clear/pinkish drainage from her left ear. Sudden onset No scratching and does not seem to have pain. She does occasionally shake her head and was somewhat unsteady yesterday. Ear infection vs?
Without actually looking into the ear with an otoscope it is not possible to tell you what the cause of this discharge is. It could be anything from an ear infection , to a ruptured abscess, to an ulcerated cancerous growth, to a ruptured ear drum. Please take Your dog to a vet , as the unsteadiness does point to some inner ear problem.

My dog is shaking his head really hard, is then tensing on one side and back to shaking his head. I think it’s his ear so I massaged them a little and tried to clean them out but he kept freaking out and is now shaking his jead a lot more
Poor Jesse! It sounds like he's quite uncomfortable. Excessive head shaking is a very common sign of an ear infection, so I would be suspicious that this may be the problem. Ear infections are quite painful and will require prescription ear drops from your vet to treat effectively, so I would recommend taking him in for an exam today if possible. Your veterinarian examine the ear canal with an otoscope and take a sample of any discharge that may be present to help diagnose the problem, and will prescribe appropriate medication to treat it depending on what is found.

I have 3 dogs, all of them have red swollen ears on the inside, head shaking. one dog seems a lot worse then the others.
It sounds like your pets may be dealing with ear infections, which can be caused by bacterial, parasitic or fungal infection, or a combination of these, and can be associated with dietary or environmental allergies or sensitivities, immune system disorders, or a combination of the above. Buddy and your other dogs need to see a vet to have an ear swab done. Your vet can look at the sample under the microscope and treat appropriately based on what is found. Your vet will also need to examine the ear with a scope to see if the ear drum is intact, as some medications cannot be used safely if the eardrum is ruptured. Ear infections can be very painful, and can sometimes progress to include the middle or inner ear, where they can cause neurological signs or permanent hearing loss. Please book an appointment to have Buddy and your other dogs seen as soon as possible to help get them feeling better.

My dog has a bloody ear, and there’s dry blood, and he keeps shaking his head, how do I treat it or should I take home to the vet
This presentation could be due to an ear infections. Three sections of the ear can be infected, the external portion (otitis externa), the middle portion (otitis media) and the inner portion (otitis interna). Otitis externa is the most common ear infection in dogs. In this case it seems an external ear infection but an otoscopic examination will determine the exactly the extension of it. A clinical examination at your local veterinarian is essential to confirm these clinical suspicions and treat appropriately. Antibiotics may be needed.

My dog has been itching his ears and shaking his head like crazy. I cleaned them out and found a puss like substance. His ears are red and very dry on the inside. What could that be?
Samson likely has an infection of his ears, likely bacterial. With this appearance he needs prescription strength medications for this to heal. Therefore he needs to go see his veterinarian so they can do an exam and prescribe the appropriate antibiotic. If left untreated some of these cases can cause permanent changes to the ears, hearing loss, chronic pain and even have resistant bacterial infections that are even more difficult to treat. So early intervention is key.

Hi there my dog has smelly yellow puss in her ears we noticed it this afternoon she seemed fine in herself but tonight she has gone very quiet and is now shaking a little
Hi and thanks for using Boop by Petco! Sorry to hear about Minnie. Sounds like she is suffering from an external ear infection (otitis externa) most commonly associated with allergies. It is also possible that Minnie has gotten water in that ear, has a foreign body in there (hair, other) or has just developed a primary ear infection not associated with an inciting cause such as allergies. I would advise taking her to your veterinarian. They will gather a history, perform an exam including the ear and then based on their findings advise you on a diagnostic/treatment plan. Your vet will most likely do an ear smear and look at the discharge under a microscope. They will be looking for ear mites, bacteria, and yeast. A malodorous yellow discharge is indicative of a severe bacterial infection. Once a cause is identified a treatment plan can be tailored to treat that cause. Possible treatments could be ear cleaning/flush (with or without sedation depending on the severity), ear drop

My dog has yellow stuff in her ear and she shakes her head and her ears are sore
It looks like Diamond has a pretty bad ear infection! Ear infections can be caused by yeast or different types of bacteria. Unfortunately without being see by a veterinarian there's not much you can do for an ear infection at home. It would be best to schedule an appointment for Diamond to see your veterinarian. Your veterinarian can make sure Diamonds ear drum is not damaged and take a swab from the ears to determine what type of infection is present and what medication should be used. I would schedule pretty soon as ear infections can be quite painful and the longer they go on the harder they are to treat. Thanks for using Boop by Petco!

My old dog has just come off a one week course of antibiotic (human form - amoxicillin) for a tooth infection. He is occasionally shaking his head and rubbing his ears against the furniture. Inside of his ear stuck to the skin was a grey/browny pad
It's probably an ear infection, often it cannot be seen from the outside. Ear infections are very common in dogs, it is usually caused by either yeast or bacterial disease. the treatment is usually simple and straightforward, you will have to take him to the vet and get the ears checked, then a prescription ear drops will be prescribed according to the infectious agent.

My husky has been shaking her head and whining while scratching the inside of her ear. I noticed when I looked inside there was a little bleeding where she scratched herself. I also found yellow green slimy stuff
It sounds like Beanie could have an infection in the ear canal. This is called Otitis Externa and can be very painful and itchy. I recommend having Beanie evaluated by your veterinarian quickly so that Beanie can get relief. Usually a veterinarian will take swabs of the external ear canal to find out what type of organism is responsible for the infection and be able to prescribe the correct medication.

My dog has thick green discharge from his ear, almost looks like dried buggers.
This discharge is likely due to an ear infection. I would take Oden into a vet now. It's very important to have this ear infection examined and treated promptly due to the discharge coming from his ear. In addition, leaving it untreated can lead to hearing loss. The vet can confirm that he does have an ear infection, and can prescribe medication to treat it.
