What are Ear Tumors?
If your pet has an ear tumor, it may be asymptomatic until it gets big enough to cause symptoms or unless it is visible. The majority of ear tumors are not cancerous and some do not even need treatment unless they are causing problems or pain in your dog. However, many veterinarians believe that it is best to remove ear tumors, whether they are in the tissues, bones, or glands, or need to be removed to prevent infection, pain, and growth. The tumors of the ear are most often small lumps on stalks growing from the skin, but they may also be a large mass in the ear, or just a flat discolored lesion. They can be black, purple, pink, white, or brown and they may be filled with blood, oil, or pus, depending on the location. Dogs with long, floppy ears, such as Cocker Spaniels, Beagles, and Golden Retrievers, are predisposed to ear tumors and having multiple ear infections may also be a risk factor.
Ear canal tumors are growths in any part of the ear, including the muscles, bones, connective tissues, oil and earwax glands, and outer, inner, and middle layer of skin. The outer ear canal and pinna area are more common than the inner or middle ear to find a tumor. Ear canal tumors in dogs are more likely to be benign (not cancerous) than malignant, but they should always be seen by a veterinary professional because these tumors can cause deafness and balance problems (among other complications) for your pet.
Symptoms of Ear Tumors in Dogs
The side effects of ear tumors depend on where the tumor is and how large it is. Some of the most often reported signs of ear tumors are:
- Visible growth in the ear
- Shaking head
- Stumbling or falling due to lack of balance
- Tilting the head
- Swelling of the ear
- Scratching or rubbing the ear
- Whining or crying in pain when ear is touched
- Foul smell in the ear
- Bloody or yellow discharge
Types
Most ear tumors are benign (not cancerous), but only a veterinarian professional is qualified to tell the difference. That being said, there are several types of ear tumors which include:
- Earwax gland tumor
- Inner ear tissue tumor
- Middle ear tissue tumor
- Outer ear tissue tumor
- Tumor of the bone
Causes of Ear Tumors in Dogs
Experts are not certain what causes ear tumors, but there are several risk factors:
- Dogs with large, floppy ears (Cocker Spaniels, Beagles, Golden Retrievers)
- History of multiple ear infections (otitis externa, otitis interna, otitis media)
- Long-term inflammation of the ear canal
- Repeated infestations of ear mites
- Thickening of the ear wax for any reason (usually unknown)
Diagnosis of Ear Tumors in Dogs
To diagnose an ear tumor in your dog, your veterinarian will need to perform a thorough physical examination, including weight, blood pressure, temperature, reflexes, pupil reaction time, heart rate, respiration rate, skin and coat condition, and breath sounds. Be sure to tell the veterinarian if your dog is on any kind of medicine, whether it is prescription or over the counter drug. Also, describe the symptoms you have noticed and how long they have been going on.
General diagnostic tests will be needed, which may include a complete blood count (CBC), chemical analysis, blood gases, liver enzyme panel, and blood urea nitrogen (BUN). If possible, a detailed otoscopic examination of the affected ear will be done to check for damage or any other tumors. Your dog will be sedated for this procedure as well as for the x-rays that are needed to look at the internal ear structure. In addition, an ultrasound, MRI or CT scan may be necessary for a more detailed examination. Finally, the veterinarian will do a fine needle aspiration for biopsy of the tumor to check for malignancy.
Treatment of Ear Tumors in Dogs
Treatment of the ear tumor depends on where it is and how big it is, but it usually involves surgery to remove the growth. Laser surgery is used if possible, as that is the safest choice. However, in some cases, the veterinarian may have to do a surgical excision or a total ear canal ablation (TECA), if there is extensive damage from the growth.
Total ear canal ablation (TECA)
Radiographs or CT scans are used to check the tympanic bullae (middle ear) and the narrowness of the ear canal. Your dog will have cultures taken to determine the best course of antibiotics to use to prevent further infection. TECA is the removal of the ear canal, which is done if the tumor has damaged or distorted the canal beyond repair. Your dog’s ear is opened up and the whole ear canal will be removed, including the bony part of the middle ear.
Recovery of Ear Tumors in Dogs
The diagnosis for ear tumors is good, but depends on your dog’s age, health, and where the tumor is located. As long as the tumor was benign, there is no reason to think your pet will have any lasting complications or shortened life span. In some dogs, the tumor may grow back, but this is very rare. However, if you notice another growth in the ear, be sure to call the veterinarian right away.

Hi , my dog is a 5 1/5 year old male neutered 95 lb blue nose pitbull . He has had several ear infections over his lifetime . About a year ago he was diagnosed with vestibular disease . For the last 2.5 weeks he has what we thought as being a flair up , lots of shaking of the head , tilted head , unsteadiness , but the worst part is he is very uncomfortable . You go to touch his head and he screeches, he tries to itch his ear , he screeches. So I brought him in to his doctor yesterday , they put him under anesthesia ( he's very hard to work on otherwise ) to check his ear canals out to see if they needed to be flushed etc . The ear that bothers him is his right ear. He said they both looked great , but due to the fact that we've done X-rays, and he is in pain , he is worried he may be missing something . He thinks with should go get a cat scan for the possibility of a tumor inside the ear. What are your suggestions? Could it be something else ? If it is a tumor that deap in the ear , what are the options of removing it or are there any?

Generally hypersensitivity around the ears would be indicative of an ear canal infection, but was ruled out by your Veterinarian. Signs of vestibular disease may present due to head trauma, tumours, inner ear infections, neurological problems or chronic poisoning; unfortunately, for examination of the middle and inner ear more advanced imaging methods (CT or MRI) are required and may not be available in your area. There are some surgical options for tumours in the middle ear (total ear canal ablation) but a firm diagnosis is needed. Regards Dr Callum Turner DVM

My Boston Terrier was diagnosed with vestibular disease when I started noticing her first symptoms. It happened literally overnight we woke up and she couldn't walk without running into things she had a lot of nystagmus so we took her to the vet and that's when they told us she had vestibular disease. The day after that she had a lot of bloody pus colored drainage from her ear as well as a head tilt I took her back in they told me that she had an inner ear infection and started her on medication. she was on a combination of steroids and antibiotics for 4 weeks to try and get rid of the infection. Last week when I went to the vet they said that her eardrum has ruptured and they've never seen a case like hers. They started to taper off of steroids and antibiotics. I was noticing her getting a little better not a hundred percent but a little better with her on the steroids but now that they are trying to wean her off she is starting to really have trouble with her balance again. My vet seems a little confused by this which makes it very frustrating for me. I hate seeing her like this. I don't feel like she's in any pain just because she's acting normal eating drinking playing and being her normal six-year-old self. But it just doesn't seem to add up as to what this is. Any advice for a defeated dog mom?

My shitzu is 10 years old. I found out she had a small tumor on her right ears 2 years ago. Her ear didn’t have infection since I clean her ears with zymox ear cleanser . I went to couple vets . Vet recommended to remove it . Last time her tumor grows bigger with infection she had tri optic oitments and antibiotics . Now I put tri optic ointment when her ear has smelll and clean it everyday
She acts normal and healthy . Vets say this is a complicated surgery on her ear tumor and would take biopsy after removed it
She will be 11 years old on next August
I don’t want she has pain from the surgery on her age . So I just watch and see. Please advise . Thanks 🙏

My 9-10 week old beagle puppy, that we got less than a week ago, woke up with a large lump on her face near the ear. This is causing her not to eat or drink as much, and she struggles to keep her head elevated. We took her to our vet, they did not know what was wrong they gave her a Dexamethasone injection, and benadryll to help with little results, it has grown a lot bigger than what it was before the injection. The growth appeared a day or two after she had her puppy shots. Any solutions?

I don't know how old my daughters dog is. The Vet guessed her age at being 4 years, but she had been with us for 3 by that point and several more years with her previous owner.
I guess her age to be closer to 7-10.
She's a pit bull/black lab mix.
She saw the vet last year for her ears. He said she has very bad allergies and prescribed an allergy med.
About 2 months ago, we noticed a large growth on the inside (c. mid point) of her floppy ears. It's light pink and larger than a 50 cent all around (almost free floating, not like a flat mole but more like a balloon). It's attached by a thinner bit of skin. I took it for a tumor.
She's nicked it a couple of times but it otherwise doesn't seem to give her much grief. The inside of her ears look pretty nasty though (gray to brown to black colored, scaly, dry but almost tar like in places). The growth now has a dimple on it which bleeds off and on.
About an hour ago, she did something to the ear with the growth and it just started gushing blood from that dimple. I went through nearly an entire roll of cheap paper towels.
My daughter doesn't get paid until the 21st (I have no income).
Can the dog bleed to death from rupturing such a growth? What can I do to help her until we can get her to the vet?

My 2 year old Pit Bull has a growth we believe to be a polyp in her outer ear. It is completely blocking the ear canal. We took her to a local vet and they suggested Surgery is TECA the only option for this removal or can this be treated with another less invasive option. ?
