veterinary B-ultrasound examination of the vulva and vagina factors causing dystocia in female dogs

The factors of the vulva, vagina and cervix of female dogs are due to congenital maldevelopment. The vulva is not fully dilated. After veterinary B-ultrasound examination, it is necessary to determine the specific plan; Immature and early mating; fibrous tissue hyperplasia or scars cause incomplete vulvar dilation. Congenital maldevelopment of female dogs; incomplete vaginal dilation caused by cysts, tumors, fibrous tissue hyperplasia, vaginal prolapse and abscesses. After veterinary B-ultrasound examination, after diagnosing such diseases, treatment methods should be considered. Congenital maldevelopment, hormone imbalance, fibrous tissue hyperplasia or scars in female dogs can cause incomplete cervical dilation.

Uterine atony Clinically, uterine atony is generally divided into three situations according to the cause. First, the mother dog does not take in enough calcium and glucose during pregnancy, which can lead to uterine atony and cause dystocia; second, the mother dog's secretion of prostaglandins, estrogens or posterior pituitary hormone is dysregulated; third, due to multiple births, excessive fetal total volume and excessive amniotic fluid, the uterus is over-expanded, or because the mother dog is pregnant with few fetuses, the fetus does not stimulate the mother's delivery insufficiently, which can be well observed on veterinary B-ultrasound. These are all factors that lead to uterine atony.

Environmental and psychological factors Changes in the production environment and accompanying people, or fear caused by strong stimulation before the mother dog gives birth. These external factors can also cause dystocia in pregnant mothers.

Placental factors, the normal placenta is attached to the posterior wall, anterior wall or lateral wall of the uterine body. Veterinary B-ultrasound observation shows that if the placenta is attached to the lower segment of the uterus, or even the lower edge of the placenta reaches or covers the internal cervical os, its position is lower than the fetal presenting part, which is called placenta previa. Placenta previa is one of the main causes of bleeding in late pregnancy and a serious complication during pregnancy. Improper treatment can lead to dystocia in the female dog. Therefore, it is also very important to observe through veterinary B-ultrasound in the early stage. Early treatment will not endanger the lives of the female dog and the fetus.
