When to Call the Vet During Dog Pregnancy
Most dog pregnancies and whelpings need no vet heroics at all. This page is for the minority that do: the specific, named red flags — in pregnancy and in labor — where “wait and see” becomes the wrong answer.
During pregnancy: call the same day if
- She passes day 68 from the first mating with no signs of labor.
- She seems genuinely ill: repeated vomiting, diarrhea, no appetite for more than a day or two in late pregnancy, fever, or marked lethargy.
- There is colored, cloudy or foul-smelling discharge (a little clear, odorless discharge can be normal).
- She stops eating entirely in the final week without the other labor signs appearing — appetite loss is normal as part of labor, suspicious on its own.
- You know she was mated but every confirmation window has passed with nothing confirmed and her shape is changing — get her seen rather than guessing.
During whelping: call immediately if
- 30–60 minutes of strong straining with no puppy.
- More than about 2 hours between puppies while she is actively straining.
- Dark green or black discharge before the first puppy — a placenta has separated early.
- Heavy bleeding at any point.
- Collapse, severe pain or obvious distress.
- A puppy visibly stuck part-way.
- Labor signs for 24 hours after the temperature drop with no progression to straining.
After whelping: the first days
Call about: a retained placenta (your placenta count does not match the puppy count) · a hot, hard, painful mammary gland · trembling, restlessness or a stiff gait in a nursing mother (possible eclampsia — an emergency) · foul-smelling discharge · or a mother who ignores, rejects or is rough with the puppies. Our newborn puppy care guide covers the puppy-side warning signs.
Being ready before you need it
None of these calls go well at 3 a.m. if you are searching for a number. Write down — on paper, by the whelping box — your regular vet's number, the nearest 24-hour emergency clinic and its address, and your day-68 date. Agree with your vet in advance what they want you to do for each flag. Preparation, not panic, is the whole system; it is why the preparation checklist treats the phone numbers as supplies.
Know your day-68 date cold: the dog pregnancy calculator puts it on the same screen as her due date and window.
Frequently asked questions
Is green discharge before the first puppy always an emergency?
Treat it as one. Dark green or black discharge means a placenta has likely separated before its puppy is born — that puppy's oxygen supply is compromised. After puppies have started arriving, some green-tinged discharge is normal. Before the first puppy: call the vet straight away.
My dog is at day 69 but seems fine. Can I wait?
Call the vet today for advice rather than deciding alone. Many day-69 dogs are fine — a later mating often explains it — but a vet may want to check puppy heartbeats and her condition, and past day 68 from the first mating is exactly the threshold the standard guidance sets.
Should I drive her to the vet or call first?
Call first whenever it is safe to: the clinic can prepare, advise whether to come in, and sometimes solve it by phone. If she has collapsed, is bleeding heavily, or a puppy is visibly stuck, do not delay transport to make calls — go, and phone from the road if someone can.
