Should Be a Master of Dog Be Afraid of Newly Appeared Bump on Ear?


A bump on a dog’s ear is usually noticed when the accompanying symptoms as redness or itching appear. This applies to small subcutaneous lumps that may appear after bruises.

If the reason lies in an allergic reaction, then there is almost always severe itching and irritation, which brings significant discomfort to the pet. With abscesses, everything is a little easier, because they are immediately visible and difficult to confuse with something.

Description of Possible Provoking Factors

A persistent blood lump on the ear in a 10 ears dog may well turn out to be a malignant tumor that must be surgically removed. In young animals, the same symptom may be the result of a recent fight or a symptom of eosinophilic granuloma, which is increasingly common in animals of different ages lately.

In any case, the veterinarian needs to determine the formation, palpate, make a biopsy and conduct a histological tests (if necessary) to exclude the following possible causes.


They can be insects or parasites. A red bump on a dog’s ear can be a symptom of flea dermatitis, which develops due to an allergy to flea saliva. Stinging insects (wasps, bees, bumblebees) and flies, gadflies can also bite a pet. The bites of the latter are very painful and are accompanied by the appearance of a hard seal, which may not go away for 2-3 days.

If the animal has severe itching and redness, then you can choose anti-inflammatory ointments or antihistamines. Bathing with a hypoallergenic shampoo, which should soothe irritated skin.


A common occurrence, especially in hunting breeds, which spend most of their life in forests and tall grass. You can get hurt by branches or weeds. In a dog, a bump appears on the outside of the ear most often after a foreign object (a needle from a weed or coniferous tree) gets under the skin.
This area of the skin can be overgrown with skin (a seal forms) or an inflammatory process begins (an abscess appears). You also need to be careful if the animal is playing or quarreling with relatives during a walk. The ears are the most commonly injured body part in dogs.

A careful determination of problem areas after each skirmish with relatives will not be superfluous, since open wounds must be treated with antiseptics.

Eosinophilic Granuloma

Usually the lower part of the head (lips, flews, oral mucosa) and neck are affected. But, lesions are also found on the ears. They look like small red bumps. They can itch, in rare cases they transform into an ulcer (usually only on the oral mucosa).

Many veterinarians associate the appearance of eosinophilic granulomas with poor nutrition, especially in ornamental breeds prone to allergies. Therefore, in the absence of open wounds (after scratching) and pain, for a start, it is suggested to use a super premium class medical hypoallergenic food for 2-3 weeks.

Usually this period is enough to notice improvements. It is also suggested to remove rubber and plastic toys (if any) and change the dishes to glass or ceramics.


If a bump is felt in the dog’s ear, then it is necessary to exclude the possibility of a tick bite.

It is not always possible to find where it stuck to the pet’s skin. This is especially true of the area of the ears, where the animal can easily reach with its paws and drop the parasite. After a tick bite, a seal almost always remains, in some cases reaching the size of a ripe cherry. Also, a red rim may appear around the lesion. Pus and inflammation will indicate an infection, which could be the source of that tick bite.

Even the slightest suspicion of a tick bite should be accompanied by increased attention from the owner. The most obvious and alarming signs of the development of piroplasmosis (which can be fatal) are red urine, refusal to eat, lethargy and cramps in the limbs.

Remember that the peak of the activity of these parasites occurs in the spring and autumn (depending on the region, of course), so during this period, the treatment of the pet with acaricidal preparations will be very useful.

It is found not only inside the ear canal. A bleeding lump on a dog’s ear may be a sarcoma or squamous cell carcinoma. And this probability increases with the age of the pet. Therefore, in animals after the age of 10 years, with the appearance of subcutaneous seals of a dubious nature, a biopsy and a histological determination are performed to exclude the possibility of oncology.

Depending on the structure of the ear (each breed has its own) and the localization of the formation, effective treatment options are selected. But, with malignant formations, the best option is considered to be surgical excision of the formation with the capture of healthy tissue within 1-3 cm.

The master’s task is to palpate in time for the subcutaneous lumps on the ears and other parts of the body of his pet. The life of the animal may depend on this.
