What does a female dog miscarriage look like – what are the symptoms of a dog miscarriage

       (1) The embryo disappears, has called the recessive abortion, is the early pregnancy embryo and the fetal membrane completely absorbed by the mother, the person already expels but has not been discovered. It is confirmed by examination that the embryo has disappeared after a period of time.

       (2) The birth of less than months of the fetus, that is, premature delivery. The performance of female dogs is similar to that of normal delivery. The symptoms before delivery are not as obvious as that of normal delivery, and the premature fetus may survive.

       (3) Birth stillbirth, is the most common abortion, occurs in late pregnancy, often dystocia. In the second trimester of pregnancy, colostrum can be extruded, but there is no fetal movement. The opening of the neck can be seen during the examination of * *, which is the symptom of the female dog before the abortion fetus is discharged.

       (4) Stillbirth arrest is a process in which the dead fetus remains in the center for a long time due to the weak contraction of the fetal matrix, the failure of opening of the fetus, and the absence of spoilage bacteria or infection in * *. It is difficult to distinguish the early stage from the pregnancy after the fetus is dried up, but the abdominal circumference of the female dog does not increase and the pregnancy phenomenon does not progress. There is no estrus. The dead fetus can also be dissolved. The soft tissue of the dead fetus is broken down and turned into liquid, while the skeleton remains in it. This form of abortion is not as much as mummification. The stagnant stillbirth may also decompose. When the fetus fails to be discharged later, the spoilage bacteria will invade the stillbirth, causing it to decompose rapidly and accumulate a large amount of gas in the subcutaneous, intramuscular, thoracic and abdominal cavity of the fetus. Especially in the hot season, the pathological changes are more rapid.

       Methods to deal with abortion:

       General abortion, such as the expulsion of the fetus less than a month or death without change, does not need special treatment. We should strengthen the nursing, disinfect the female dog’s part, and give the nutritious and digestible feed. If the fetal death is not discharged, and the neck has been opened, intramuscular injection of pituitrin 0.5-1 ml can promote the expulsion of the dead fetus, or extract the fetus according to the principle of midwifery.

       When the fetus is mummified, if the dog has opened, a large amount of warm soapy water can be poured into the dog, and then try to extract the dried fetus. If the neck has not been opened, 2-3 mg of diethylstilbestrol can be injected intramuscularly. In most cases, the fetus can be withdrawn after 2-5 hours. If the above methods are ineffective, the injection should be repeated every two days, or the neck of the penis should be expanded gradually with fingers, and then the fetus should be extracted.

       For the diseased dogs with fetal invasion, diethylstilbestrol should be injected first to dilate the neck. If necessary, the injection can be repeated every other day. ***After the neck was dilated, 0.01% potassium permanganate solution was injected into the femoral neck and washed repeatedly, and the bone was removed. Finally, rinse again and inject appropriate amount of antibiotics.

       When the fetus decomposes, if the fetus is abnormally enlarged, the fetus can be deflated, and then it can be pulled outwards. If necessary, the fetus can be amputated and cleaned with a large amount of antibiotics.

       There are many reasons for canine abortion, including the following:

       Various mechanical injuries. Such as abdominal collision, impact, trauma and abdominal surgery, it is very easy to cause abortion.

       A variety of infectious diseases. For example, brucellosis often does not appear abnormal on the outside, but abortion occurs in 45-55 days of pregnancy. Canine distemper, tuberculosis, infectious hepatitis and so on also increase the incidence of abortion.

       Parasitic diseases. When a female dog has toxoplasmosis, it can also cause abortion.

       ***Official disease. Chronic endometritis, abnormality of sperm and fetal membrane, etc.

       Maternal endocrine disorders. Such as hypothyroidism and progesterone secretion is insufficient.

       In addition, abortion may be caused by various systemic diseases, improper feeding and lack of nutrition.

       The maintenance structure of pregnant female dog and fetus is the vulnerable part in the body. After any adverse factors act on the mother, it is the first to suffer the damage to the mother and the fetus. Therefore, only by comprehensive and careful management, disease prevention and control, can we ensure the safety of pregnancy.

       Key points of diagnosis

       Clinical diagnosis is generally easier, such as the discovery of pregnant female dog less than months that occurs abdominal Nuo, discharge live or dead fetus can be diagnosed. It should be noted that most cases do not necessarily see the process of abortion and the expulsion of the fetus, but only the outflow of the secretion. In the recessive abortion in the early pregnancy, because the embryo has been absorbed by * *, there is no abnormal change in * *. In such cases, a comprehensive examination should be carried out on the female dog. First, the nutritional status and other diseases should be checked. Then, the abdominal wall should be carefully palpated to determine whether there is still a fetus in the dog. Sometimes only one or several fetuses conceived by a female dog miscarry, and the remaining fetus may continue to grow until the full-term pregnancy, which is called partial abortion.

       It is very important to diagnose the cause of abortion. Only by clarifying the cause of the disease can we determine whether the sick dog can continue to breed and what kind of treatment should be adopted. If a female dog suffering from brucellosis can no longer be mated and pregnant, even if she is pregnant, she will eventually have to miscarry. The diagnosis of etiology is complicated, and many tests should be done, such as serological test, hormone determination, urine analysis, microbial culture of * * secretion, etc. Conditional, but also to abortion fetus to do all kinds of examination. Therefore, after abortion, the owner should send the fetus to the veterinary inspection unit for examination.

       The treatment methods were as follows

       When the signs of miscarriage appear in the female dog, measures should be taken to protect the fetus. Progesterone can be injected intramuscularly into the sick dog at a dose of 2-5 mg / time for 3-5 days. And symptomatic treatment.

       If the sick dog is weak, infusion and sugar should be given in time. When the body temperature rises and the blood picture shows inflammatory changes, antibiotics should be injected. Oxytocin and other oxytocin drugs should be injected (the dosage is 2-10 units / time) for fetal dystocia, retained fetal membranes or bleeding. In addition to the injection of antibiotics, it is also used in the cases of fetal corruption. The genital tract was washed with 0.1% permanganate solution.

       In order to prevent miscarriage, it is necessary to check the mother dog for brucellosis and other infectious diseases before mating. We should strengthen feeding management during pregnancy. For the female dogs with abortion history, progesterone can be injected during pregnancy to prevent abortion.

       If you are not sure whether the dog miscarriage, or can not implement treatment on your own, it is recommended that you take it to a professional pet hospital for treatment!

       Dog abortion refers to the physiological function disorder of the mother or fetus, which destroys the pregnant relationship between the mother and the fetus and causes pregnancy interruption. It may be manifested as complete absorption of the embryo, or expulsion of live, dead, or decayed fetuses. The causes of the disease are mainly divided into infectious and non infectious.

       1¡¢ Causes of dog abortion:

       1. Infective abortion: that is, the mother by bacteria, viruses, protozoa and other infections and abortion.

       2. Pulmonary infectious abortion: mainly due to endocrine disorders, such as pregnant dogs, cats estrogen too much and progesterone deficiency or lack. ***Official diseases such as endometritis, although pregnant, but affect fetal development. Improper feeding, incomplete nutrition, inbreeding, stress reaction or severe diseases of other maternal systems and external force can all cause abortion.

       2¡¢ The performance of dog abortion:

       1. Threatened abortion: the pregnant dog * * flows out transparent or translucent jelly like mucus, sometimes mixed with blood, clinical manifestations of restlessness, rough breathing and rapid pulse.

       2. Invisible abortion: at the beginning of pregnancy, before and after blastocyst implantation, the fetus has not yet formed. After the embryo died, the embryo was liquefied and absorbed by the mother, leaving no trace, and the female dog had no obvious symptoms.

       3. Preterm birth: the labor omen is not obvious, only in 2-3 days before excluding the fetus, * * suddenly increases, * * swells, * * flows out cool mucus, and discharges dead or inactive fetus. No fetal movement reflex was found during abdominal palpation. The external neck opening was slightly opened and mucus was thin.

       4. Delayed abortion: pregnancy interruption, fetal death. Due to the weak or no contraction of the antenna, the opening of the neck is not large or not, and the stillbirth remains in the center for a long time.

       3¡¢ Treatment and care of dogs after abortion:

       1. Need tocolysis and protection. When the mother dog is found to have threatened abortion, timely give sedatives and birth protection drugs, such as intramuscular progesterone.

       2. Promote fetal discharge. ***When the neck is opened, the fetal membrane has been broken, and fetal water flows out of the fetus, oxytocin can be used to promote the contraction of the fetus. ***When the neck is not opened properly or not, and when the fetus is mummified, diethylstilbestrol can be used to promote the discharge of the postmortem fetus. If the fetus is too large and abnormal posture, any of the above methods can not be taken out, then induction of labor or fetal amputation will be carried out to remove the fetus.

       3. Treatment of fetal dissolution. Estradiol or surgical methods can be used to expand the neck, take out the fetal bone, and rinse after operation to prevent infection.
