TL;DR: Green discharge in a pregnant dog is a critical emergency if a puppy is not born within 15 to 30 minutes, as it indicates life-threatening placental separation. Immediate veterinary intervention is necessary to save the mother and her puppies.
What does it mean if my pregnant dog has green discharge?
Green discharge in a pregnant dog is usually caused by a pigment called uteroverdin, which is released when the placenta separates from the uterine wall. While this is a normal occurrence during the active birthing process, seeing it before labor begins or without the arrival of a puppy is a major cause for concern.
Why is green discharge in a pregnant dog considered a medical emergency?
- Green discharge is a high-urgency medical emergency if a puppy is not born within 15 to 30 minutes of its appearance.
- The presence of the discharge indicates that the placenta has detached, which compromises the puppies' oxygen supply.
- This situation often points to fetal distress, stalled labor, or a potential infection, requiring immediate veterinary intervention to save the mother and pups.
How does taking a photo of the discharge help the veterinary triage process?
- A clear photo allows the medical team to visually confirm the color, viscosity, and amount of the discharge.
- Having a visual helps the triage nurse prioritize your case more accurately.
- The clinic can prepare the necessary diagnostic tools or surgical equipment before you even arrive.
Clinical Context (Merck Veterinary Manual)
During canine parturition, a green vaginal discharge (uteroverdin) is normal. However, immediate veterinary attention is warranted if a dark green discharge is observed before the delivery of any neonates, as this indicates placental separation.
