Dog Surgical Diseases – Abortion

Abortion

Cause

There are many reasons for miscarriage, roughly as follows:

Various mechanical injuries. If the abdomen is hit by collision, impact, trauma, and abdominal surgery, it is very easy to cause miscarriage. Many infectious diseases. For example, female dogs suffering from brucellosis often have no abnormal appearance, but miscarriage occurs within 45 to 55 days of pregnancy. Canine distemper, tuberculosis, and infectious hepatitis also increase the incidence of miscarriage.

Parasitic disease. When a bitch suffers from toxoplasmosis, it can often cause miscarriage.

Reproductive organ diseases. Chronic endometritis, abnormal sperm and egg, abnormal placenta and fetal membranes, etc. Maternal secretion disorders. Such as hypothyroidism and insufficient progesterone secretion. in addition. Various systemic diseases, improper feeding, nutritional deficiencies, etc. may cause miscarriage . The structure of the uterus and fetus of a pregnant bitch is the fragile part of the body, and any unfavorable factors act on the mother’s body. The first to be hurt is the uterus and fetus. Therefore, only a comprehensive and careful start with feeding management, disease prevention and other work can ensure the safety of pregnancy.

Diagnosis points

Clinical diagnosis is generally easy. If a pregnant bitch is found to be pregnant within a month, it will be diagnosed with abdominal pain and discharge of a live or dead fetus. It should be noted that in most cases, it is not always possible to see the abortion process and the discharged fetus, but only the vaginal discharge. Recessive abortion that occurs in early pregnancy, because the embryo has been absorbed by the uterus. There were no abnormal changes in the vagina. In these situations, a comprehensive examination of the bitch should be done, first to see the nutritional status, whether there are other diseases, and then carefully palpate the abdominal wall to determine whether there is still a fetus in the uterus. Sometimes only one or a few of the fetuses in the bitch have a miscarriage. The remaining fetuses may continue to grow until they are delivered at term pregnancy, which is called a partial abortion.

Diagnosis of the cause of miscarriage is very important. Only by clarifying the cause can we determine whether the sick dog can continue to breed and what treatment methods should be used. If a bitch suffers from brucellosis, it can no longer be bred for pregnancy, even if it is pregnant. Eventually there will be a miscarriage. The diagnosis of the etiology is more complicated and requires a number of laboratory tests, such as serological tests, hormone determinations, urinalysis, and microbial culture of vaginal secretions. If conditions permit, various inspections must be done on aborted fetuses. Therefore, after a female dog has a miscarriage, the dog owner should send the delivered fetus to the veterinary inspection unit for inspection.

Prevention

When the bitch shows signs of miscarriage, it is necessary to take precautionary measures. Progesterone can be injected intramuscularly to sick dogs at a dose of 2 to 5 mg/time for 3 to 5 days, with symptomatic treatment.

If the physique of the sick dog is weak, it is necessary to infusion and sugar supplement in time. When the body temperature rises and the blood picture shows inflammatory changes, antibiotics should be injected. For symptoms such as difficulty in expelling the fetus, retention of placenta, or uterine bleeding, oxytocin and other oxytocin drugs should be injected (the dosage is 2-10 units/time). In cases where the fetus has become corrupt, in addition to the injection of antibiotics, 0.1% potassium permanganate solution is also used to flush the reproductive tract. In order to prevent miscarriage, the bitch should be checked for infectious diseases such as brucellosis before breeding. Feeding management should be strengthened during pregnancy. For female dogs with a history of miscarriage, progesterone can be injected during pregnancy to prevent miscarriage.
