How to treat mastopathy in dogs?

Dog mastopathy is a benign mammary gland tumor. This is quite common (more than half of all tumors) in dogs, which is usually found in females older than 6-7 years.

Most often, tumors occur in the fourth and fifth pair of mammary glands, are rare in the first and second pair. This is due to the fact that the fifth functional pair of mammary glands has the greatest functional activity. Initially, a single tumor appears and if measures are not taken, the neoplasms may be multiple.

The appearance of a tumor is usually associated with estrus, pregnancy in a dog or false shit. With these functions, the mammary glands are always enlarged, and after - they return to normal. However, when pathologies in the tissue appear abnormal formations. They can be elastic or soft, they can shine through the skin.

Forms of mastopathy in dogs

Mastopathy can be diffuse and fibrocystic.

  • Diffuse form begins with the appearance of pain in the mammary glands, which occurs a few days before estrus. This form may precede fibrocystic. When palpating in the mammary glands, there is a feeling of a bag with a shot.
  • Fibrocystic form characterized by the formation of dense painful nodes that grow rapidly without treatment. This form of mastopathy is more common in older dogs older than 6 years. Consolidation in the mammary glands can be single or multiple and always pronounced.


  1. The main symptoms of mastopathy in dogs is an increase in the mammary glands, and when probing, there is a noticeable graininess, lobulation and veinness in them.
  2. There may be various secretions from the nipples: colostrum, ichor, blood.
  3. A dog may experience pain, lick glands, be restless, even “pull a paw” from the side where the glands are affected. A tumor nodule may not change its size for a long time or grow very slowly, compacting after estrus or during false motion.
  4. If the tumor is not detected in time and treatment is not started, the dog begins to lose weight quickly, refuses to eat, drinks a lot. It is weakened and apathetic, an increase in the nearest (regional) lymph nodes is felt.
  5. If the tumor continues to grow, germinating in the surrounding tissue. The skin around the tumor becomes hot and tense, losing hair.
  6. Ulcers and suppuration of individual areas may occur.
  7. At the last stage of the development of the disease, a dog may cough, which indicates a metastatic lesion of the internal organs. This means that the tumor has become malignant.

Since the fibrocystic form of mastopathy can have quite different symptoms and the most unpleasant consequences (including the formation of precancerous tumors), if signs of mastopathy are found, you should consult a specialist as soon as possible or call the veterinarian at home. An accurate diagnosis can be made only by examining the contents of the education with the help of histology.

Treatment of mastopathy

  • At the initial stage of the disease, the doctor simply observes the animal and regularly examines it during estrus and sham.
  • It is possible to use homeopathic preparations, which, in a stable condition, allow the nodes to be held for a long time or even lead to their disappearance.
  • Hormonal therapy is also often used to treat the diffuse form of the disease.
  • If mastopathy has a fibrocystic form and the tumor grows, surgical intervention is necessary. However, not every old animal will be operated on, it depends on the age, concomitant diseases of the liver, heart, kidneys and the extent of the spread of the tumor.
  • As a result of the operation, the prognosis for further recovery is not always favorable, recurrences and individual metastases may occur.

If the dog’s tumor is large and metastasis begins, the operation is already meaningless. However, sometimes the doctor and in such a situation, makes the so-called palliative surgery: removes most of the bleeding or decaying tumor, and the effect of anti-tumor drugs is used on its residue. True, such actions lead to a slight extension of life, but not a cure for the animal.
