Infertility in female dogs continued

 
SUBINVOLUTION OF PLACENTAL SITES

After birth, the places inside the uterus where the placentas were attached must heal and the uterus must reconstruct itself. While this occurs, a bloody and greenish/black discharge may be noted from the vagina.{{more}} When these “sites” do not heal normally, rather, more slowly than normal, it is termed sub-involution of placental sites and a persistent bloody discharge will occur. Clinical signs will simply include a bloody discharge lasting more than 6 weeks after whelping. Diagnosis is based on this symptom, vaginal cytology, X-rays and blood counts.

TREATMENT OF SUBINVOLUTION OF PLACENTAL SITES

Some dogs need no treatment and may heal in time. Spaying is advised if further breeding is not wanted. Antibiotics to prevent infection and the use of drugs to contract the uterus have proven useful.

ABORTION (SPONTANEOUS)

Disorders or defects of the mother, pups or placenta can all result in termination of pregnancy. Uterine disease, ovarian disease, fetal deformities, infections, including brucellosis, leptospirosis, herpesvirus, ehrlichiosis (tick fever) other organisms and certain drugs, can all result in spontaneous abortion.

Clinical signs may or may not be observed other than no puppies being born when expected, depending upon the stage at which a given pregnancy was ended. Discharge or passing puppies prematurely may be observed. Fever, loss of appetite, vomiting and diarrhea can all occur. Acute metritis and pyometra are common post-abortion side effects.

TREATMENT OF ABORTION

While little can usually be done after the fact, dogs should receive medications to clean out the uterus, antibiotics to prevent infection and spaying if it seems preferable to no longer breed the bitch. It is important to obtain a proper diagnosis, as again, some causes of spontaneous abortion are communicable and need aggressive treatment to stop their spread.

To be continued next week.
