Endometritis in a dog: symptoms and treatment

Treatment of endometritis in dogs is a complex of therapeutic procedures that are aimed at eliminating the inflammatory process and healing the animal. Endometritis (pyometra) is an inflammation in the uterine lining. Most often, such a pathology is combined with an accumulation of pus in the uterus and is accompanied by a serious condition of the dog. If you do not take the measures on time, death can occur.

The reasons

The most common cause of this pathology is hormonal imbalance. This condition causes a thickening of the uterine walls, the accumulation of a large amount of secretory mucus. As a result, the secretion is released from the body in the form of serous fluid, acute inflammation develops. The pyometer begins after bacteria enter the organ cavity. That is why vaginitis, diseases of the genitourinary system, some diseases of the genitals can cause this condition.

If the puppy is in childbirth, the animal also gets sick (the fetus decomposes in the womb, bacteria appear that provoke inflammation). In these cases, endometritis is particularly difficult. If in the process of childbirth the owner decided not to wait for the obstetrician and independently remove the fetus by hand, without antiseptic agents and sterile gloves, infection can also occur.


The main signs of this disease in acute form (symptoms appear several days after infection) include the following:

  • a change in the general condition of the dog, worsening of mood, the appearance of a feeling of weakness and apathy;
  • discharge from the genitals of grayish mucus with impurities of pus;
  • fever;
  • frequent posture in which urination usually occurs (even if the dog does not want to urinate);
  • vomiting
  • rapid loss of fluid by the body (the animal is constantly thirsty);
  • frequent urination (in some cases, the dog begins to urinate at home);
  • change in heartbeat (this can be tracked on your own, just put the ear to the chest of the animal);
  • difficulty breathing, it becomes more severe and intermittent (as a result of disruption of the heart muscle);
  • if the treatment was not prescribed on time, the dog loses its coat, increased pigmentation of the skin due to hormonal imbalance is observed.

If the animal has not been treated for an acute form of malaise, it can develop into a chronic one. In this case, the following symptoms are observed:

  1. Violation of the duration or frequency of estrus.
  2. Severe weight loss.
  3. The appearance of weak puppies that can die during or immediately after birth.
  4. Difficulties with conception, in the future there may be complete infertility.

Please note: all these signs can indicate not only the development of endometritis, but also the appearance of other diseases of the gynecological sphere. That is why, at the first symptoms, it is important to consult a qualified veterinarian who will diagnose, accurately identify the pathology and prescribe timely therapy.

Diagnostic Features

After you go to the veterinary clinic, the doctor will collect a medical history and study your pet’s medical history. In this case, be prepared to answer questions regarding the frequency of estrus, pregnancy and childbirth, as well as the color and consistency of secretions from the genital organs of the animal.

After clarification of these issues, a dog is examined. The specialist measures body temperature, determines the condition and color of the mucous membranes of organs, probes the peritoneum. If the diagnosis could not be clarified, additional studies are prescribed.

To determine the symptoms and prescribe treatment for endometritis in the dog, the veterinarian performs ultrasound diagnostics, during which it is possible to determine the state of the uterine cavity. Laboratory diagnostics are also carried out (general analysis of urine and blood to determine inflammation).

If during the diagnosis, violations of the heart muscle are detected, the dog is sent to an ECG, during which it is possible to exclude the presence of heart disease. Based on the information received, an accurate therapeutic regimen is prescribed.


First of all, the doctor prescribes drugs that restore the balance of water and salts in the body if the animal has suffered from vomiting for a long time and dehydration has occurred. If the dog’s body temperature is elevated, medications with an antipyretic effect are prescribed.

To eliminate inflammation, a course of antibiotics is prescribed. The minimum treatment period is ten days, if necessary, the veterinarian can extend the course. If the drug has no effect on pathogenic microorganisms, bacteriological culture is prescribed. Such an analysis makes it possible to accurately identify which antibiotic is capable of destroying certain bacteria.

Please note: antibiotic therapy is prescribed only by a veterinarian, self-administration of drugs by the owner is unacceptable. Taking medications is carried out under the supervision of a specialist in order to avoid the development of side effects.

If you went to the doctor too late, surgery is performed. During the operation, the surgeon removes the uterus, and in some cases, the appendages. The operation is prescribed if there is a high risk of organ rupture due to accumulated purulent discharge (if a rupture occurs, the dog will inevitably die). After surgical manipulation, the animal will be under stationary observation, specialists monitor the functioning of organs, including the work of the heart muscle. To exclude the appearance of a postoperative infectious process, antibiotics are prescribed.


To prevent inflammation of the uterine tissue in the dog, the owner should take care of proper prevention. Since the main cause of the pathology is hormonal imbalance, it is important to consult a doctor at the first symptoms, as well as regularly conduct preventive examinations and, if necessary, take blood tests.

Monitor the bearing of the fetus in the animal, timely conduct ultrasound diagnostics in the early stages. This will make it possible to exclude the presence of a false pregnancy, which must be urgently treated, otherwise the risk of inflammation increases several times.

Periodically conduct an independent examination of your pet. If you notice that the nature of the discharge from the genitals has changed, immediately make an appointment with a veterinarian (this will allow you to timely identify vaginitis and other gynecological pathologies).

Many owners neglect dog hygiene. This should not be done. Do not forget to regularly wash the dog and monitor its behavior: do not let walks near garbage containers, carefully care for the hair and do not allow contact with other animals that have an untidy appearance and signs of illness.

Pay particular attention to childbirth. The best option is to call a veterinarian who will monitor and control the process. If you had to provide emergency care yourself, use sterile medical gloves and antiseptic solutions (such as miramistin or chlorhexidine).

Be careful, otherwise genital tears may occur. After first aid, show the animal to the doctor in the near future so that he is convinced of the normal course of childbirth. With careful monitoring of your animal, the chance of developing acute and chronic endometritis is reduced to zero, therefore prevention is based on caring for the dog.

Thus, endometritis is a pathology that is dangerous for the reproductive function of the pet, and in some cases for its life. If there are suspicious symptoms of the disease in the female, make an appointment with a specialist who will prescribe a full treatment.
