Pyometra in dogs is a fairly common disease. It appears spontaneously within 2-3 months after estrus in middle-aged and older animals.
It is believed that the disease is caused by prolonged stimulation with progesterone, which is characteristic for the period of metestrus, as well as a complication of a secondary bacterial infection. Pyometra may also occur as a result of hormonal therapy, which prevents estrus or interrupts unwanted pregnancy in females of all ages.
Symptoms of pyometra in dogs
In spontaneous cases, the disease develops gradually over several cycles.
- Initially, the only symptom may be discharge from the vulva - slimy and insignificant. If an animal at this stage is left without treatment, the disease continues to develop, polyuria, polydipsia and malaise appear, discharge from the vulva increases, becomes more bloody, and leucorrhoea appears.
- Against the background of these symptoms, fever can also begin, during which the symptoms become apparent.
- When feeling the abdomen the dog resists due to pain. An increase in the uterus is felt. However, with a rough probe, there is a risk of uterine rupture. Therefore, ultrasound is preferable.
To clarify the diagnosis, a blood test is also taken, urine is examined.
