It is not possible to detect pus in the ear of a dog immediately, because not every master will conduct a daily or weekly examination of his pet. Worst of all, when the animal does not allow such examination and the problem is already detected in an advanced stage. This is especially true of otitis, which is very common in all breeds from early childhood. In older individuals, the same symptom can be an alarming sign for the development of a malignant tumor inside the auricle.
Description of the Most Common Causes
The presence of pus inside the ear canal indicates the presence of an inflammatory process that can be caused by various reasons, ranging from the ingestion of a foreign object and ending with the tumor process. A lot of attention is paid to concomitant symptoms by which the following possible options can be excluded or suggested:
- Foreign object. One of the frequently occurred cause of pus in a dog’s ear is ingestion of plant seeds, food debris, insects, branches from trees and other objects that can trigger an inflammatory process. Given the complex structure of the auricle in many breeds, it is very difficult to extract a splinter. If this is not done, the process will be complicated by redness, fetid odor, bleeding and severe itching. The animal must be shown to the veterinarian who will conduct an external determination and take the discharge for a cytological tests, according to the results of which it will be clear whether there is a bacterial infection or not. The foreign body itself in most cases can only be seen with the help of special equipment. The splinters are removed using special exciting tools. After this, antiseptic treatments of the affected areas are carried out. Antibacterial and anti-inflammatory drops may also be prescribed.
- Trauma. Hunting breeds are at risk because of the peculiarities of the structure of the ears and long stays in places with difficult potency (forests, tall grass, bushes). An animal can get damaged on the sharp edge of a branch, a spike of a weed or shrub. Pets are also most often injured when walking through the woods or tall grass. But, one cannot be excluded the possibility of injury during a game or a fight with other animals. Especially dangerous are scratches from the claws of cats, which are very often fester. If pus is found in the dog’s ear, it is necessary to carefully determinate the organ for integrity of the skin and the absence of splinters. Scratches after claws and bites from teeth must be treated with an antiseptic solution. You can also use the ointment, which is applied to the affected area 2 times a day until complete healing.
- Neoplasms. If the dog has pus in the ear without visible damage on the skin inside or outside, then it is worth considering the variant with the formation of polyps. These are benign formations that are most often localized in the middle ear. In adults, it is necessary to exclude the likelihood of malignant tumors, which often occur after 10 years age. In addition to purulent discharge characteristic symptoms are a fetid odor, squelching sounds during shaking the head with a pet, and severe itching. As a rule, the process is localized in the region of one affected organ of hearing. To make a diagnosis, MRI of the head, a biopsy, a cytological and histological determination of the obtained materials will be required. When confirming the malignancy of the process, removal of the ear canal is indicated. The prognosis is highly dependent on the stage of the tumor and the presence of metastases.
- Bacterial damage. It can also be the cause of pus inside a dog’s ear. Especially after deep scratches from claws or bites from teeth. In time, untreated wounds often become inflamed and fester. In veterinary medicine there are even such types of otitis media – purulent and bacterial. In addition to injuries, their appearance can be triggered by deep wounds after scratching, foreign bodies, parasites and allergies. Typical symptoms are redness of the skin inside the auricle, the presence of dirty unpleasantly smelling secretions and itching, due to which the pet scratchs his temples and behind his ears to sores. It is possible to determine the type of bacteria using a cytological examination of fluids and secretions taken from the affected organ. After that, antibacterial drops and ointments are selected. But, without exception, the root cause, treatment may be in vain.
If the dog has pus in the ear, it behaves strangely (shakes its head, scratchs the temples, tilts its head to one side), then it is better not to delay a visit to the veterinarian, as advanced otitis is very difficult to treat, especially in breeds suffering from food allergies and atopic dermatitis.
