Home / Breeding / Whelping Guide
Whelping is the word breeders use for a dog giving birth. Most healthy dogs whelp naturally and competently, and the owner's real job is threefold: prepare the space and supplies well in advance, recognize what normal labor looks like, and spot the handful of situations where minutes matter and a veterinarian must take over. This guide covers all three, in that order.
Strong straining for 30 to 60 minutes with no puppy born. More than 2 hours between puppies when more are expected. Green or black discharge before the first puppy, with no puppy following quickly. A puppy or membrane stuck partway out. Stage one lasting beyond 24 hours. A temperature drop more than 24 to 36 hours ago with no labor. Pregnancy past its due window with no labor. Heavy fresh bleeding, collapse, extreme pain, fever, or a mother who is trembling, disoriented or ignoring a puppy in distress. When in doubt, phone: vets would always rather reassure you early than meet an emergency late.
Set the whelping area up by about day 50, in a warm, quiet, draft-free part of the house where the mother already feels safe and other pets cannot wander through. The centerpiece is a whelping box: a low-sided box or pen big enough for her to stretch out fully, with a guard rail (often called a pig rail) running around the inside a few inches off the floor, so a puppy that wriggles behind her cannot be trapped against the wall. Line it with layers of washable bedding you can strip and replace quickly; whelping is messy and the bedding will change many times in the first days. Introduce her to the box daily from setup onwards, feed treats in it, and let her nap there, so that when labor starts she heads for the box by choice. Keep the room warm: newborn puppies cannot regulate their own temperature, and the area immediately around them needs to feel comfortably warm to a bare forearm for the first week.
In stage one the uterus contracts and the cervix dilates, but there is no visible pushing and no puppy can be born yet. Outwardly she may be restless, pace, pant, shiver, dig at and rearrange her bedding, refuse food, vomit once, seek you out or seek solitude, and pass a little clear mucus discharge. This stage is often at its most invisible in first-time mothers and at its most theatrical in experienced ones, and both are normal. Your tasks are simple: confirm her temperature drop if you caught it, keep the room calm and dim, offer water, take her out for a toilet break on a lead (puppies have been born in gardens by owners who skipped this precaution), and start your written record. If stage one runs beyond about 24 hours without progressing, that is a vet call.
Stage two begins when abdominal pushing starts. She will usually lie on her side or squat, strain in bouts, and lick at her vulva. A water bag or membrane may appear first, then the puppy, usually delivered inside its membrane. Puppies arrive head-first or tail-first; both are normal in dogs. The mother typically breaks the membrane, licks the puppy vigorously to start it breathing, and chews through the cord herself. If she is busy with the next puppy or ignores a newborn, step in calmly: tear the membrane from the face, clear the mouth and nose with the bulb device, rub the puppy firmly but gently with a towel until it cries and wriggles, then place it against her to nurse. A puppy every 30 to 60 minutes is a typical rhythm, each individual delivery should take well under 1 to 2 hours of effort, and she may rest quietly between puppies, sometimes for an hour or more, which is normal as long as she is not straining unproductively.
Each puppy has its own placenta, delivered shortly after the puppy, so stages two and three alternate until the litter is complete. The mother will usually try to eat the placentas; one or two is harmless, but eating many can cause vomiting and diarrhea, so remove later ones discreetly as they arrive and, importantly, count them. Placentas passed should equal puppies born. A missing placenta, or foul-smelling discharge in the days after, is a reason to have the vet check her, since retained tissue can cause a serious uterine infection. This is also where your puppy-count X-ray from week 7 or 8 pays for itself: knowing the expected number is how you know the difference between a finished whelping and a long pause with one puppy still inside.
Dystocia means a difficult or blocked birth. The common causes are an uterus that tires or never contracts properly (uterine inertia), a puppy that is oversized, wrongly positioned or deceased, a narrow birth canal, and, most dangerously, delay: problems compound quickly because a separated placenta starts a countdown for its puppy. The red-card signs are listed in the panel at the top of this page. Veterinary help ranges from examination, monitoring and carefully judged medication, which only a vet should give, oxytocin in the wrong situation can rupture an uterus, through to a cesarean section, which is the definitive answer to a blocked birth and the reason your emergency fund and your vet's number both need to be ready before day 58. Do not attempt home remedies, internal examinations or pulling on a stuck puppy: the margin between help and harm here is professional knowledge.
When the last puppy and placenta are out, replace the bedding with clean, dry layers, offer the mother water and a light, energy-dense meal, and let the family settle in the warm. Each puppy should be dried, breathing well, and nursing; the first milk, colostrum, carries antibodies the puppies cannot make for themselves, so confirm every puppy latches within the first hours. Weigh each puppy and record it; daily weights for the first fortnight are the simplest health monitor there is, since steady gain means feeding is working. Watch the mother for fever, hot or painful mammary glands, foul or heavy discharge, trembling or restlessness days later (possible low calcium, an emergency), and loss of interest in the litter. Most vets like to examine mother and litter within the first day or two; book it before you finally sleep.
Before the day arrives: follow the week-by-week guide and get your dates from the pregnancy calculator. Back to the breeding hub.
The most reliable signal is a drop in rectal temperature to below about 100 F (37.8 C), usually 12 to 24 hours before the first stage of labor. Behavior follows: restlessness, nesting, panting, shivering, loss of appetite and wanting to be alone or glued to you, depending on the dog.
Stage one, the quiet preparation stage, lasts about 12 to 24 hours. Stage two, active delivery, typically produces a puppy every 30 to 60 minutes, with each puppy taking no more than 1 to 2 hours of effort, and the whole stage usually finishing within 24 hours, often much faster. Stages two and three alternate, puppy then placenta, until the litter is complete.
Call your vet if more than about 2 hours pass between puppies while she is still straining or still has puppies left to deliver, if she strains hard for 30 to 60 minutes with no puppy, or if a green discharge appears with no puppy following promptly. Resting quietly between puppies is normal; unproductive straining is not.
Most healthy dogs deliver without any physical help, and the best assistance is usually a calm room, clean supplies and watchful patience. Help is for specific moments: clearing a membrane from a newborn's face if the mother does not, drying and stimulating a quiet puppy, and phoning the vet early when the emergency signs below appear.
Green or dark discharge seen before the first puppy is born means a placenta has separated from the uterus while its puppy is still inside, which cuts off that puppy's oxygen supply. It turns the situation urgent: if a puppy does not follow very quickly, this is an emergency vet call, not a wait-and-see.
Usually the mother chews each cord herself, and that crushing action helps seal it. If she ignores a cord, you can tie it with clean thread about an inch from the puppy's belly and cut on the far side of the tie with clean scissors. Never pull on a cord, and never cut one that is still under tension from a placenta inside.
