Whelping puppies successfully comes down to preparation, knowing what normal labor looks like, and recognizing when something has gone wrong. Most healthy dogs deliver their litters without complications, but having the right supplies ready and understanding the timeline of labor can make the difference between a smooth delivery and a preventable emergency.
Signs That Labor Is Approaching
Starting about two weeks before the expected due date, take your dog’s rectal temperature twice a day at the same times. A dog’s normal temperature sits between 100 and 102.5°F. Within 24 hours of labor starting, her temperature will drop below 99°F. This dip typically lasts about eight hours and is one of the most reliable signals that puppies are on the way. Not every dog shows a detectable drop, so watch for behavioral changes too: nesting behavior, restlessness, loss of appetite, and panting.
Setting Up the Whelping Area
Have your whelping box ready at least a week before the due date so your dog can get comfortable in it. Place it in a quiet, warm area of your home away from foot traffic and other pets. The box should be large enough for your dog to stretch out fully but have sides high enough to contain the puppies while still letting her step in and out easily.
Gather your supplies well in advance:
- Bulb syringe for clearing fluid from puppies’ noses and mouths
- Clean towels and washcloths for drying puppies and stimulating breathing
- Umbilical clamps or hemostats to clamp cords that bleed
- Iodine solution for dipping umbilical stumps
- Latex gloves to protect the mother from bacteria on your hands
- Digital thermometer for monitoring the dam’s temperature
- Scale for weighing each puppy at birth and tracking daily gains
- Chlorhexidine solution for keeping the whelping box sanitized
- Washable liners or pads for the bottom of the box
- Notepad to record each puppy’s birth time, weight, and whether its placenta was delivered
What Normal Labor Looks Like
Labor happens in three stages, and stages two and three repeat with each puppy.
Stage One: Pre-Delivery
This stage can last 6 to 12 hours, sometimes longer in first-time mothers. Your dog will be restless, may pant heavily, refuse food, shiver, or vomit. She may dig at bedding or pace. The cervix is dilating during this time, so you won’t see visible straining. Your job here is to stay calm and nearby without hovering. Keep the environment quiet.
Stage Two: Active Delivery
Visible contractions begin, and your dog will actively push. Each puppy is born enclosed in a fluid-filled membrane. The mother will normally tear this membrane open, chew through the umbilical cord, and lick the puppy vigorously to stimulate breathing. Let her do this. Most dogs handle it instinctively.
If she doesn’t break the membrane within a minute or two, you need to step in. Tear the sac open near the puppy’s face, clear fluid from the nose and mouth with a bulb syringe, and rub the puppy firmly with a clean, dry towel. This rubbing mimics the mother’s licking and stimulates the puppy to take its first breaths. You should hear crying, which is a good sign.
Stage Three: Placenta Delivery
A placenta follows each puppy, sometimes immediately and sometimes with the next puppy’s delivery. Count every placenta and write it down. Each puppy has one, and a retained placenta can cause serious infection. If one is visibly hanging partway out, do not pull on it. A foul-smelling, dark green or black discharge after whelping is complete, combined with fever or lethargy, can signal a retained placenta that needs veterinary attention.
The mother may eat some of the placentas. This is normal behavior, though eating too many can cause vomiting or diarrhea. Allowing her to eat one or two is fine.
Handling Umbilical Cords
Most mothers chew the cord themselves, leaving a short stump. If she doesn’t, clamp the cord about an inch from the puppy’s belly and tear or cut it on the side away from the puppy. Avoid cutting too close to the body. Dip the stump in iodine solution at birth, then again at two hours, eight hours, and twice daily until the cord dries and falls off. This prevents bacteria from traveling up the cord and causing infection.
Clearing a Puppy’s Airway
A vigorous puppy that cries right away just needs a gentle wipe around the nose and mouth with a clean cloth. For a puppy that isn’t breathing well or seems limp, use a bulb syringe to suction fluid from the nostrils and the back of the mouth, then rub the puppy briskly with a towel. Keep the puppy’s head slightly lower than its body to help fluid drain.
Do not swing puppies. This was once common advice, but veterinary guidelines now recommend against it because of the risk of brain injury. Gentle suctioning and vigorous towel-rubbing are safer and effective.
Getting Puppies Nursing Quickly
Each puppy needs to nurse within the first few hours of life. The first milk, colostrum, delivers antibodies that are critical for survival. Puppies are born with almost no immune protection of their own, and the antibodies in colostrum can only pass through the intestinal wall during a narrow window. Absorption is most effective within the first 8 hours and drops off sharply by 12 hours. After 16 to 24 hours, the gut closes and the puppy can no longer absorb these protective antibodies at all.
This means every hour counts. Guide each puppy to a nipple between deliveries if the mother is calm enough to allow nursing while still in labor. Smaller or weaker puppies may need extra help latching. If a puppy cannot nurse, contact your veterinarian about supplemental colostrum options.
Timing Between Puppies
Puppies can arrive anywhere from 15 minutes to over an hour apart. It’s common for a dog to rest between deliveries, sometimes for an hour or more, especially with larger litters. She may nurse the already-born puppies during these breaks. This is all normal.
What is not normal, and requires an immediate call to your veterinarian:
- Strong, active pushing for 20 to 30 minutes without producing a puppy
- More than 2 to 4 hours between puppies with no signs of contractions
- Active labor (stage two) lasting longer than 12 to 24 hours total
- A puppy visibly stuck in the birth canal
- Green or black discharge before the first puppy is born, which can indicate placental separation
These are signs of a difficult birth that may require veterinary intervention, potentially including a cesarean section. Have your vet’s emergency number and the nearest after-hours clinic number posted where you can see them.
Keeping Puppies Warm
Newborn puppies cannot regulate their own body temperature. The whelping area should stay around 85 to 90°F for the first week of life. A heat lamp positioned safely above one side of the box (so puppies can move away if too warm) or a heating pad set on low beneath a layer of bedding can maintain this. Monitor the temperature at puppy level with a thermometer rather than guessing.
Feeding the Mother After Whelping
A nursing dog’s caloric needs climb dramatically. At peak lactation, roughly 2 to 3 weeks after delivery, she needs about twice her normal caloric intake. Feed a high-quality puppy food or a diet formulated for lactating dogs, as these are calorie-dense and higher in the nutrients she’s burning through. Offer food in multiple smaller meals throughout the day rather than one or two large ones, and keep fresh water available at all times. She will drink significantly more than usual.
Watch for Calcium Deficiency
One of the most dangerous postpartum complications is a sudden drop in blood calcium, which peaks in risk at 2 to 3 weeks after whelping, right when milk production is highest. Small-breed dogs nursing large litters are most vulnerable. Early warning signs include panting, restlessness, and pacing. As it progresses, you may see muscle tremors, stiffness, disorientation, aggression, whining, excessive drooling, and hypersensitivity to touch or noise. This condition escalates quickly and can be fatal without treatment. If your nursing dog shows any combination of these signs, treat it as an emergency.
The First Few Days
Weigh each puppy at birth and then daily at the same time. Healthy puppies should gain weight every day. A puppy that loses weight or fails to gain for more than a day needs attention, as it may not be nursing effectively or could be getting pushed off the nipple by stronger siblings. Keep the whelping box clean by changing liners whenever they’re soiled. Monitor the mother’s discharge: a mild reddish-brown discharge is normal for up to three weeks. Foul-smelling discharge, fever, or loss of interest in the puppies signals a problem.
During the first week, puppies spend almost all their time sleeping and nursing. The mother handles stimulating them to urinate and defecate by licking them. If she isn’t doing this, you can gently wipe each puppy’s belly and genital area with a warm, damp cotton ball after feedings to trigger elimination.
