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 (polyps), 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 locations for tumours 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 even benign 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
- Chronic ear infections
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 or 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 and the narrowness of the ear canal. Your dog will have cultures taken to determine the most appropriate 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 prognosis for ear tumors is good, but depends on your dog’s age, health, and where the tumor is located. As long as the tumor is 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.

My pet has the following symptoms:
Head Tilt
Nystagmus
Trouble Walking
Drainage
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?

Head tilt/vestibular disease may be attributable to infections, trauma, idiopathic causes, tumours, poisoning among other causes; from your description it does sound like a severe infection which would need aggressive antibiotic treatment and cleaning. If your Veterinarian is confused, I would recommend speaking with another Veterinarian in your area to get their input on treatment as well as possibly sending a sample off for culture and sensitivity if the current treatment seems ineffective.

My pet has the following symptoms:
Pain
Fatique
Swollen Head In Ear Region
Smell In Ear
Drooping On Right Sign Of Head
Scratching The Ear
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 am not sure what the growth is; it could be due to an enlarged salivary gland, a skin lesion or another cause. I cannot examine the lump, but I would have thought your Veterinarian may have taken a fine needle aspirate of the lump to see what the contents is and to see if it could be drained or not. I would keep an eye on it for now, but it needs further investigation. Regards Dr Callum Turner DVM

Foul smelling lesions are normally caused by necrotic tissue, infection or both; it would be best to have your Veterinarian take a look and to advise you on cleaning, they may do an initial clean to show you the best way. Cleaning the areas without a dilute antiseptic may help a little, but some systemic antibiotics may be required; a course of antibiotics or other medication may be required in case of infection.
