The dog's uterine empyema has a long period, and it is difficult for the owner to find it at the early stage of the disease. There are many reasons for purulent uterus in dogs. The main reason of dystocia is that the bitch is overnourished during pregnancy and the fetus is abnormal. During childbirth, due to too many fetuses, some fetuses are too large, and uterine muscles continue to contract, so that fetuses cannot enter the birth canal and stay in the uterus, forming uterine empyema. And a bitch who never gave birth. So how to diagnose whether dogs have this disease? What are the clinical symptoms?

First, how to diagnose

1. Diagnosis of closed pyometra

Abdominal palpation showed that the uterine horn and uterine body were obviously thickened, sometimes cystic, fluctuating obviously, and there was a certain pain response. The vulva changes are not obvious and clean, and it is easy to draw out thin pus when puncturing the uterus.

2. Diagnosis of open uterine empyema

When palpating the uterus, the uterine horn is thick and the wall is thick, the sense of fluctuation is not obvious, the pain response is obvious, the vulva is polluted by pus, it smells bad, and the vulva is red and swollen. Only a small amount of pus can be extracted when puncturing the uterus. After general anesthesia, press the abdomen and more pus will be discharged from the vulva.

Second, the clinical symptoms

1.*** Same symptoms.

After 3-8 weeks of estrus, it occurs frequently, with fever at first, listlessness, loss of appetite, decreased activity, lethargy and sometimes vomiting. With the development of the disease course, the appetite gradually disappears, the desire for drinking gradually increases, the dog becomes thin, the abdominal circumference increases, and physical failure occurs.

2. Closed pyometra

Accounting for 59.6%(28/47) of the statistical cases. The cervix is completely blocked, the vulva has no purulent secretion, the abdominal circumference is large, and the breathing and heartbeat are accelerated. In severe cases, it is difficult to breathe, the abdominal skin is tense, and the subcutaneous vein of the abdomen is bulging, making it easy to lie down.

3. Open pyometra

This kind of cases accounted for 40.4%( 19/47). The cervical canal was not completely closed, and a small amount of purulent secretions flowed irregularly from the vulva, which was cheese-colored, gray or reddish-brown, with an unpleasant smell and often polluted the vulva, tail root and tarsal joint. Dog vulva is red and swollen, vaginal mucosa is flushed, and abdominal circumference is slightly increased.
