Is a Lump on a Dog’s Сhin a Reason for Concern?


Lumps on the body of dogs are redensifications that may be ranging in size from a few millimeters to 3-5 centimeters. They can be found on any part of the body of an animal – such morbid growth can be observed on the head, back or limbs of the dog. A lump on the dog’s chin (chin pyodermia) can be triggered by transmissible diseases. Among other possible exciting causes traumatic furunculosis is often mentioned. Short and hard hairs, shifting from the hair follicle to the opposite direction, traumatize it, and thus launching observed reaction to a foreign object. At a later stage, these areas of epidermis may become infected.

Chin pyoderma can be triggered by certain traumatic factors: continual lying on a hard surface, mechanical friction against various toys. Chin pyoderma is a characteristic phenomenon in young (from 2 months to 1 year) and short-woolled breeds of dogs.

The disease declares itself in the form of nontender comedones, hard lumps, cyst encapsulations, papules. In severe cases, ulcerative fistulas with serohemorrhagic contents can appear on the chin or muzzle. On gentle palpation, the hairs may be squeezed out of the follicles.

A lump on the dog’s chin can be triggered by various causes. The morbid growth can be due to both serious diseases and common insect bites. Some bumps can go away without exterior help, others can cause considerable discomfort to the animal. And in order to prevent any serious occurrences it is better not to postpone the visit to a veterinary specialist.

Possible etiological factors

Various factors may instigate the appearance of lumps on the dog’s chin:

  • pathogenic bacteria;
  • viral diseases;
  • chin injury;
  • mechanical agent (damages);
  • insect bites (ticks, bees);
  • oncological condition.

For differentiation, scraping should be performed. The result of the test allows the veterinary to identify the causes of the disease.

Types of Morbid Growth

All redensifications on a dog’s body can be divided into certain groups: non cancerous lumps and malignant (cancerous) tumors.

Noncancerous Lumps

  1. Papillomas and warts often occur in smooth-coated breeds of dogs. Scholars contend  the small lumps may be a triggered by a viral infection that lingers in the body of a pet. Warts appear in the form of a brown dermis emerod. Typically, they are nontender. As a precaution, it may be advisable to visit a veterinary.
  2. Cyst encapsulations. Those may show themselves anywhere on the dog’s body and on the chin as well. Most often, the swelling is detected by chance, and not in the course of a scheduled inspection. If the lumps are on the head or a muzzle of a pet they are rather noticeable.
  3. Hematomas. Bumps of such origin are typically spotted in the postsurgical period, especially with damage to blood vessels. These mamelons are soft on palpation, may change slightly the shape of the body part of their localization. Most often, hematomas are nontender, but the animal still may experience some discomfort.
  4. Insect bites. Lumps caused by insect bites stick out noticeably on the muzzle and chin of a pet.
  5. Abscesses are usually triggered by bacteriological contamination. Development of an abscess is possible after bites and puncture wounds. An abscess is characterized by hypodermis inflammation and a fever heat. These evidence may come with algesthesis. Tumorogenesis takes up to several days. Pyorrhea is a possible symptom.

Tumor masses can be divided into two groups

Benign neoplasms are notable for the absence of metastases and restriction of its biodisposition. Typical redensifications can reach significant proportions, and thus most guardians are insistent on the benign growth being removed. Malignant swelling can metastasize (spread) eating away surrounding tissues and organs. Lumps can provoke bleeding due to the rupture of dermis. Cutaneous findings may not bring significant discomfort to the animal and retain constant size for a long period of time. The size and solidity of the morbid growth may vary depending on its origin and histological structures.

What Should Be Done?

Upon detection of a lump on a dog’s chin, you may need to carefully examine and palpate (probe) it. If upon gentle pressing on the lump, the animal feels pain, an immediate visit to a veterinary specialist should be made. If the lump brings obvious discomfort to the dog or new ones appear, the veterinarian first of all identifies the trigger. For this purpose, a number of necessary tests can be prescribed: biopsy, radiography, sampling, computed tomography.

If the lumps do not cause pain or show different distinctive characteristics or gather matter, the guardian should closely observe the condition of the pet for several days, in some cases, the swellings may go away on its own.
