A lump on dog’s head can be of a different nature. The cause of a swelling could be both serious health problems and common bite of a bee. Some lumps resolve themselves in a few days without causing discomfort. Others need to be treated by a veterinarian.
Causes of Lumps
There are many factors that can provoke the emergence of lumps, including:
- Mechanical damage to the skin.
- Insect bite (tick or bee).
- Bacterial infection.
- Viral infection.
- Damage of blood vessels after surgery.
All formations, which appear on the head of the animal, can be divided into 2 categories: malignant and benign. The last formations include:
- Papillomas and warts. They are often found in dogs of short haired breeds, and their reason is a viral infection. Such a soft lump on dog’s head looks like a blotch on the skin and does not cause discomfort. A visit to the veterinarian in this case is recommended for the purpose of prevention;
- Cysts. Such formations can be observed in any part of the body. Moreover, such swelling is often identified by accident, not during a routine inspection;
- Hematomas. This tumor is often formed in the area of the ears of the pet. The cause of the formation is a recent operation, especially with damage to blood vessels. Also, the cause of hematoma is excessive fluid accumulation. These lumps usually have a soft texture, and they can change the shape of the area of the body where they were formed. Usually hematoma does not cause pain, but there are exceptions;
- Pyoderma. As a result of this disease a lump on dog’s head under skin occurs around the age of four months, hitting the sex gland. Unfortunately, experts still have not been able to identify the exact cause of this disease. The disease can be provoked by accelerated growth of internal organs or their sensitivity. It is simply impossible to predict the occurrence of such formations. Such lumps are able to strongly blush, exude pus, and then spread further through the body of the pet;
- Bites of different insects. If an insect bites the dog in the mouth or in the face the lump is especially noticeable;
- Abscesses. These formations occur when bacteria gets into the animal’s body. Such tumors most likely appear if the pet has suffered from bites or stab wounds. With an abscess, the temperature rises and the subcutaneous layer swells. Usually such lump is accompanied by painful sensations. They can develop over a different period of time, but often one day is enough. In some cases, there is a discharge of pus from the wound.
In its turn, a solid bump on the head of a dog may indicate the presence of a tumor:
- Benign tumors. Such swellings, unlike cancer, are characterized by the fact that they do not metastasize and do not spread throughout the body of the animal. At the same time, this formation can be very large, so it should be removed notwithstanding a benign character;
- Malignant tumors are able to metastasize, spread rapidly throughout the body, starting with nearby tissues. Such formations may be the cause of bleeding as the result of damage of the skin.

What to Do when the Problem Occurs?
Note!In case you find a lump on dog’s head above eye, or any other place, first of all you should examine it and touch carefully. If the tumor is painful for the animal, it is recommended to urgently see a doctor.
If a lump causes serious discomfort to the animal or other formations begin to appear over time, the veterinarian should first of all determine the reason why they occur. In this case, an extensive list of studies is required, among which we need to highlight:
- Computer tomography;
- Taking a smear-print.
In case the lump does not cause pain to the animal, does not emit pus and does not change its hue, the owner of the dog should watch the lump during a few days. It is likely that such swelling will pass off by its own. Remember that it is necessary to prevent the animal from licking the area of inflammation, as this may be the cause of the granuloma. If the lump begins to change, you should show the dog the vet urgently.
