Species: Dog
Condition: Uterine Inertia, Primary
Organ System: Urogenital
Uterine inertia is characterized by the failure of a bitch to expel the fetus normally. This is a common cause of dystocia in dogs and the problem has been identified as primary or secondary. Primary uterine inertia has been described as the total or partial absence of uterine contractions which are needed to expel a normal fetus through an open birth canal. The potential causes of the condition include breed disposition, large litter that caused overstretching of the uterus, a small litter that fails to exert enough pressure on the uterine wall and cervix, and the presence of an underlying systemic disease. Your veterinarian may conduct a physical examination to pinpoint the presence of the fetus in the birth canal and assess the uterine and vaginal muscle tone. A lack of response to vaginal pressure indicates the existence of uterine inertia. Radiographic tests and ultrasound can help assess the number, size and viability of the fetus. Medical treatment can first be attempted if the bitch is in good condition however a C-section may be indicated if the dog does not show response to oxytocin administration or the fetuses are too large for the birth canal.
