Whelping is the most time-critical event covered anywhere in this Knowledge Bank — a normal labor can unfold safely with minimal intervention, but recognizing the point where it stops being normal, quickly, is what genuinely matters. This area is built to work both as reading you do in advance and as fast reference in the moment.
The most important first
- Most whelpings proceed normally, but knowing what “normal” looks like is what lets you spot a deviation early.
- This area covers the whole arc: signs labor is near, the stages of labor, when it deviates, and the dam’s recovery.
- Several articles here are flagged as emergency-relevant — written to be useful read quickly, in the moment.
- Having your vet’s contact details, including out-of-hours, ready before labor begins is not optional.
- Recovery and postpartum health matter as much as the whelping itself, and are easy to under-prepare for.
What this area covers
This area moves through whelping in the order it actually happens: the signs that whelping is near, what a normal whelping looks like, and the stages of labor step by step, so you know what to expect before it starts. It then covers monitoring and documentation — including a whelping log — because good records matter both during labor and afterward. A cluster of articles addresses when whelping doesn’t go to plan: warning signs, dystocia and malpresentation, and cesarean section, all written for fast reference during an actual event. The area closes with newborn resuscitation, the dam’s first 24 hours, lactation, postpartum complications, and when to call the vet — covering both the acute event and what follows it.
Before labor starts
Ask your vet about an x-ray from about day 55 of pregnancy. Knowing how many puppies to expect is the only reliable way to tell whether whelping is finished or has stalled. Save your vet’s daytime and out-of-hours numbers, and agree in advance where you would go in an emergency.
Higher-risk bitches
Difficult births are more common in brachycephalic breeds (such as Bulldogs, French Bulldogs and Pugs), in very small breeds, in older or overweight bitches, and with very large or very small litters. If your bitch falls into one of these groups, discuss a whelping plan — including whether a planned cesarean is advisable — with your vet well before the due date.
After the birth
The first days and weeks after birth carry their own emergencies. Eclampsia — a dangerous drop in blood calcium, most often in the first weeks of nursing and more common in small breeds — shows as restlessness, panting, trembling, stiffness or seizures, and needs urgent veterinary care. A hard, hot or painful mammary gland, a fever above 103 °F (39.5 °C), or a foul-smelling discharge are also reasons to call your vet.
Why some articles here are marked emergency-relevant
A handful of articles in this area are flagged specifically because they need to work differently from the rest of the Knowledge Bank: read calmly in advance, they build understanding; read urgently during an actual whelping complication, they need to be scannable and immediately actionable. If you’re reading this while labor is already underway and something seems wrong, go straight to when whelping doesn’t go to plan: warning signs rather than reading this guide in full first.
How this area connects to the rest of the Knowledge Bank
Whelping follows directly from pregnancy — the due date and whelping area preparation covered there feed directly into this area. Once puppies are born and past the immediate whelping event, the neonatal period takes over as its own distinct area, because newborn puppy care in the following weeks asks for a different kind of ongoing attention than the whelping event itself.
When to call your vet
- She strains strongly for 20–30 minutes without producing a puppy.
- Weak or on-and-off contractions continue for about 2 hours with no puppy (never wait more than 4 hours).
- More than about 2 hours pass between puppies and you know more are expected.
- Green or black discharge appears before the first puppy — call immediately.
- Labor has not started within 24 hours of the temperature drop, or she reaches about day 70 from the first mating.
- She has a fever above 103 °F (39.5 °C), heavy bleeding, collapses, trembles or seems very unwell.
- If in doubt, call — your vet would rather hear from you early.
Work on it
A few minutes here will teach you more than re-reading the article.
Ask yourself
- Do I know the signs that whelping is imminent, well enough to recognize them without looking them up in the moment?
- Do I know where in this area to go quickly if something seems wrong during labor?
- Is my vet’s contact information, including out-of-hours, somewhere I can find it instantly?
Find out & check
- Find out your vet’s specific advice for what counts as “too long” between puppies for your bitch.
- Check that you’ve read through the warning-signs article in advance, not planning to read it for the first time during an emergency.
Do one thing
- Bookmark or print when whelping doesn’t go to plan somewhere accessible during labor.
