The miscarriage of a female dog is caused by the disorder of the fetus or dog's mother during the development of the fetus or dog's mother. Generally speaking, dogs have much fewer miscarriages than other large and medium-sized animals.
There are many reasons for dog miscarriage, and there are roughly the following: various mechanical injuries. If the abdomen is hit, impact, trauma and abdominal surgery, it is very easy to cause miscarriage.
1. Causes of miscarriage in female dogs:
1. Among infectious cases, the most common is a miscarriage caused by the infection of Brucella in dogs. This bacteria is highly contagious, especially beagle dogs, which are very susceptible. Sick dogs can also infect people and cause miscarriage to pregnant women. Secondly, when infected with Staphylococcus, E. coli, and Salmonella, abortion can occur in elderly female dogs. Occasionally infected with canine distemper virus caused by miscarriage.
2. Deficiency of corpus lutein hormone. Generally, there are incomplete corpus luteal formation in pregnancy, and there are early degeneration of corpus luteal.
3. Trauma stimulation, improper breeding and management of pregnant female dogs, medical errors, etc. can also cause miscarriage.
2. Symptoms of miscarriage in female dogs:
1. Abortion caused by Brucella usually occurs on the 30th to 57th day of pregnancy; incomplete abortion in corpus luteum, which is common in the 2-5th week of pregnancy; and early degenerative abortion in corpus luteum is more common in the 6th to 7th week of pregnancy. In all miscarriages, more than 80% of female dogs occur on the 45th day of pregnancy. (Although there are also miscarriages caused by early embryo death on the 10th to 35th day of pregnancy, the excreted membrane and fetus are often eaten by female dogs and are not easily discovered).
2. Usually, after a miscarriage of a pregnant female dog, secretions continue to flow out from the vagina for a long time (1 to 6 weeks), and the miscarriage of the fetus dies quickly.
3. The incidence of fetal malformations in early pregnancy is very high. Deformed fetuses are mostly chest insufficiency, sternum deformation, etc.
4. Non-infectious miscarriages often occur without early symptoms and suddenly occur.
3. Diagnosis of miscarriage for female dogs:
1. Diagnosis of brucella infection can be confirmed by the isolation and culture of the aborted fetus or placenta (or female dog serum agglutination test).
2. If a toxoplasmosis is suspected, the fetus' organs can be examined, especially the fetus' protozoa or tissue sections can be used to determine it. It can also be diagnosed by the female dog's blood complement combination reaction.
4. Treatment of miscarriage in female dogs:
1. Dogs often suffer from sudden miscarriage and are almost uncontrollable. To prevent miscarriage, the female dog should be checked for infectious diseases such as brucellosis before breeding. For female dogs with a history of miscarriage, progesterone can be injected during pregnancy to prevent miscarriage.
2. For dogs suspected of lack of lutein hormone, use progesterone oil 5~25mg, intramuscular injection 2-3 times a week; or use 25mg, intramuscular injection once a week.
3. If the sick dog is weak in constitution, use timely infusion and supplement sugar. When body temperature rises and blood signs are inflammatory, antibiotics should be injected.
4. For symptoms such as fetal excretion difficulties, inability to lower the seborrhea or uterine bleeding, oxytocin and other inflammatory drugs should be injected (dose is 2-10 units per time). In cases where the fetus has decayed, in addition to injecting antibiotics, 0.1% potassium permanganate solution is also used to rinse the reproductive tract.
