What happens if a pregnant mother dog has diarrhea?

Causes include diet, parasites, hormone-driven gut changes, or viral disease. Frequent diarrhea loses water and electrolytes, risking dehydration and imbalance, even life-threatening. It also reduces nutrient absorption, affecting the fetuses.

Severe diarrhea in early pregnancy can cause miscarriage, preterm birth, or defects. Drugs for diarrhea may harm fetuses, so see a vet promptly.
