Whelping emergencies: the timers
Most whelping goes fine without you. The job of the humans in the room is to know the handful of clocks that mean it isn't going fine — and to have already answered the question that sinks people at 2 a.m.: which emergency hospital near you actually does C-sections.
This page decides WHEN to call — never how to intervene. No repositioning, no pulling, no medication doses live here; those decisions belong to the vet on the phone with the dog in front of them. If any timer below runs out, the plan is the phone, then probably the car.
The timers
Timers run in this open tab only — they're a bedside aid, not a monitoring system. The rules they encode are the standard published dystocia thresholds; your vet may give you tighter ones for your breed or your bitch, and theirs win.
Call the vet without a timer if you see
- Green-black discharge before any puppy has arrived. After the first puppy, green is normal placental pigment; before it, it can mean a placenta has detached while its puppy is still inside — the 15-minute rule above exists for exactly this.
- Fresh bleeding beyond light streaking, at any point.
- A puppy visibly stuck — half-delivered, or a bubble at the vulva that strains without progressing.
- The bitch is sick, not just tired: vomiting repeatedly, trembling or seizuring (late-stage calcium crashes are real), fever, collapse, or gums going pale.
- Past 65–66 days from ovulation/breeding with no labor — that's a call-today, and ideally a conversation you had with your vet last week.
- Fewer puppies than the X-ray count and labor has stopped. A late-pregnancy radiograph for a count is cheap insurance precisely for this moment.
The breeds that earn extra paranoia
Flat-faced breeds — bulldogs, Frenchies, Bostons — carry dystocia risk an order of magnitude above average (big heads, narrow pelvises; many lines are effectively planned-C-section breeds), and singleton litters, giant heads, tiny toy bitches, and first-timers over five years all raise the odds. If that describes your whelping, the preparation below isn't optional homework, it's the plan.
The 2 a.m. question — answer it this week, not that night
Not every emergency clinic does C-sections at night: some lack a surgeon on shift, some divert. The single highest-value hour of whelping prep is phone calls before the due date: call the emergency hospitals near you and ask three things — "do you perform emergency C-sections overnight?", "what's the typical cost range?" (commonly $1,500–$5,000+ after hours; know the number before you're deciding at 3 a.m.), and "do you want a heads-up call when labor starts?" Tape the winner's number to the whelping box next to this page's timers. If the cost side is the frightening part,read this before, not after.
