Brucella in dogs most commonly causes abortion at what stage of gestation?

Brucella, particularly Brucella canis, is known to infect dogs and can lead to reproductive issues, primarily abortion. The most common stage of gestation for abortion caused by Brucella in dogs is between 45 to 60 days. During this period, the developing fetus is particularly susceptible to infection and the immune response of the mother is engaged in a way that can lead to pregnancy loss.

This specific timing correlates with the period when the fetal tissues are becoming more complex and when Brucella can exert its detrimental effects, leading to the breakdown of the placental barrier. Abortion can occur following infection not only due to direct effects on the fetus but also as a response from the mother’s immune system to the infection. In veterinary practice, recognizing this critical timeframe can assist in diagnosing and managing cases of Brucella in pregnant dogs, allowing for timely interventions to minimize reproductive losses and enhance the health of the breeding population.
