10 Best Practices for Whelping Puppy Litters

Having everything ready for the whelping box a week before the litter is due, will help you and your girl feel prepared for the big day, or evening, as it often turns out.

These best practices are based on my personal experiences as an AKC Breeder of Merit, as well as tips and videos shared with me by friends in the dog breeding community. Using these tools and techniques will ensure a successful puppy whelping!

Puppy Whelping Supplies

Here is the checklist of items you will need for whelping your litter. We will discuss the uses of each of them in depth throughout this article series.

  • A quiet area away from other dogs and family activities
  • Whelping Box
  • Digital Thermometer
  • Hemostats
  • Sharp stainless steel scissors
  • Betadine
  • Styptic powder
  • Lots of old towels
  • Yogurt or vanilla ice cream in the fridge
  • Small Kitchen scale that can weigh up to 10 pounds
  • Large water bucket


  • Heat lamp
  • Oxytocin syringes
  • KY Jelly and a syringe
  • Bulb Syringe Aspirator

The items listed under optional, such as KY Jelly and the aspirator bulb, are frequently recommended for whelping. I have them on hand, but I have never found a use for them. We will discuss the benefits and dangers of oxytocin in depth, in the Whelping Problems article.

Step By Step Guide to Building a Whelping Box

Swimming Pool Whelping Box

The MagnaBox Whelping Box

Selecting Your Whelping Box

There are many plans online for building your own whelping box. If you choose to build your own whelping box, make it out of corrugated plastic or plywood that can be purchased at Home Depot.

Plastic is easy to clean, sterilize and move around, while wooden boxes can be extremely heavy, and are more absorbent and more likely to harbor germs and parasite spores from one litter to the next.

If you choose to make it out of wood, then line it with vinyl flooring for quick cleaning.

However, if you are not handy, there are a variety of solutions to choose from:

The plastic swimming pool is a favorite for those with limited funds, and is my personal option. They are easy to clean, and have raised areas, often shaped like little fish, that help the puppies get a grip as they motor around the whelping pool. Plastic swimming pools four feet in diameter can be found at Lowes or Walmart in the summer for less than five dollars.

The problem I have with the swimming pool is puppies climbing up on the mothers side and then escaping over the edge of the pool by accident. I therefore need an exercise pen to keep them from ending up somewhere where I can't reach them.

The Dura-Whelp Whelping box versus the Plaza MagnaBox

If you are looking at a high-end, professional solution and are planning on future litters, you may want to consider a professionally made whelping box. They offer several advantages that the swimming pool lacks.

The Dura-Whelp is made from corrugated plastic, which is somewhat flexible and not as durable as the solid plastic of the MagnaBox. When Dura-Whelp was initially marketing their whelping boxes, they estimated that they would be good for whelping up to 3 litters.

I know many breeders who have used them on 15+ litters, so Dura-Whelp is now marketing them as “durable.” Prices for the Dura-whelp range from $149 for the small to $229.00 for the extra large. However, Dura-Whelp has many little add-ons you will need, such as the half-height door to let mom out and keep puppies in. These add-ons and shipping costs increase the price approximately an additional $100, depending on the size box you order.

The Plaza MagnaBox is built to last, and will stand up to puppy teeth better that the Dura-Whelp. However it has no bottom, so you will need to put in whelping pads or use the Home Depot rubber-backed, carpeted garage mats to protect your floors. These garage mats are about $19.00 for a 3x6' mat and are easy to hose off.

Prices for the MagnaBox range from $399 for the small to $599.00 for the large, with free shipping.

Both whelping boxes are equipped with rails to prevent the mother from crushing her puppies against the side of the box wall. Swimming pools cannot be equipped with this feature.

Additionally, each manufacturer offers expansion boxes as additions to the whelping box. My friends who have added on the expansion units tell me that it speeds puppy potty training. The puppies sleep and play in one box, and eliminate in the other box.

Both are tool-free assembly and easily breakdown for storage.

Setting Up The Whelping Area

Choose a quiet room that can be closed off from the rest of the household. Typically the mother will be very protective of her puppies for the first 2-3 weeks. She will not want strangers to visit the puppies, and usually will not want other animals from the household to peek in on her pups. In fact with some overprotective mothers, visits from rival females can provoke fights. Better safe than sorry, you don't want the mother to be injured, and unable to care for her pups.

As I mentioned above, if the room is carpeted, you can purchase inexpensive, carpeted rubber-backed garage mats at Home Depot to protect the carpet. Frequently, mothers will not have their first puppy in the whelping box. First time mothers may feel panicky and try to hide under furniture or may even begin labor in your lap.

Once she has had her first puppy, and you place it in the whelping box, she will have the rest of her puppies in the designated whelping area.

Bring your girl with you as you setup her room. She will be curious about your activities and the new items, and it will help her to bond with her special space.

Timing the Delivery

A week before your dog is ready to give birth, you should have an x-ray done to get an accurate count of the puppies she is expecting. This will let you know if there is trouble, should she stop labor when there are puppies still to be born.

This is a good time to discuss with your vet your options should you need an emergency C-section after hours. Your vet may be willing to come in, or may suggest that you go to an emergency clinic. You will need to shop around for pricing at various emergency clinics in your area. In my area a scheduled C-section runs about $900.00, while an emergency after hours C-section can run up to $3000.00.

If you are expecting a small litter, and the puppies are already quite large, you may opt to schedule a C-section to avoid a difficult labor.

By day 57, you will want to start taking her temperature in the mornings and evenings to get a baseline for her normal temperatures at different times of the day. Her temperature should range between 101 and 103 degrees. Anything higher than 103 degrees could indicate an infection, and merits a call to the vet.

12 to 24 hours before delivery, her temperature should begin to drop. With some girls it will drop and rise for a day or two before delivery. Some never experience a temperature drop, so keep an eye on her behavior. 12 to 18 hours prior to labor, the expecting mother will stop eating.

Once her temperature drops and stays down, it is time to keep her in her whelping area.

The First Stage of Labor

During the first stage of labor the mother will be restless and will begin nesting behaviors. She may paw at the towels in the whelping box, creating piles of towels, and then stand up and lie down repeatedly. I had one girl who made piles of leaves under an outdoor lawn chair as the first sign she was going into labor. Another pulled the stuffing out of the bottom on an upholstered chair.

She may pant heavily and then breath normally for several hours prior to the next stage of delivery. This restless cycle of revving up and calming down can go on for up to 24-30 hours.

Second Stage - Hard Labor

The second stage is marked by her water breaking and active contractions. When the water breaks depending on the size of your dog, you can expect about 1/2-1 cup of pale tea colored liquid in the whelping box. Check the time when you see her water break or contractions begin. If she has not delivered after 1.5-2 hours, you will want to begin making arrangements to see your vet.

You will see her sides heaving as see clamps down on contractions and then releases. Some girls will also grunt with each contraction. Typically within 30-40 minutes she will produce the first puppy. Puppies will tend to come in pairs 20-30 minutes apart. Then she will rest for 45 minutes to 1.5 hours while the next pair lines up the the birth canal. During the rest time she will clean her puppies and let them nurse. Nursing stimulates the contractions for the next pair of puppies.

Puppy Delivered with Amniotic Sac Intact

The First Puppy's Delivery

As the puppy is being delivered, the mother will frequently lick her vulva. Normally the puppy will arrive with the amniotic sac intact followed by the placenta attached via the umbilical cord. The sac is a thin semi-transparent film covering the puppy.

My girls begin by consuming the placenta and umbilical cord, then they work on the puppy. Often, they have already removed the sac as the puppy was coming out of the birth canal. You can sit back, and see if she can do it all on her own. I tend to be very hands-on. I prefer to cut the umbilical cord myself, and if the sac is intact, I will want to get the puppy breathing as soon as possible.

Not all mothers know instinctively what to do when delivering their first litter. Luna hid in fright under an end table after she delivered her first puppy, leaving it up to us to remove the sac and umbilical cord. As the litter continued to arrive, she caught on, and was able to handle the last couple of puppies herself.

Assisting Delivery - Removing the Amniotic Sac and Umbilical Cord

If the puppy has delivered normally, and the mother is munching on the placenta, begin by opening the amniotic sac at the head and clearing any mucus away from the puppy's nostrils and mouth. Some people use the bulb aspirator to try to suck mucus out of the airways. I find it clumsy, and that my finger and a soft towel work well to clear them. If the puppy is not breathing yet, use your finger to gently clear the back of the throat.

The puppy will gasp when he takes his first breath. Don't panic about them not breathing immediately, if the umbilical cord is still attached he will be continuing to receive nutrients and oxygen through it for another minute or so.

If the puppy still does not breath, rub him gently but vigorously with a hand towel. You are trying to simulate a mother's vigorous licking, which normally starts the puppy breathing. (If the puppy still does not breath, see the next article on Whelping Problems).

To cut the umbilical cord, take the hemostats and clamp them 3/4 of an inch from the stomach of the puppy. The hemostats simulate the action of the mother's gnawing teeth, and will prevent the umbilical cord from bleeding after you cut the cord. Cut the cord next to the hemostats on the side opposite of the puppy. You can apply styptic powder to the cut end, but it is not necessary. Remove the hemostats.

I choose to cut the cord myself, when given the opportunity, for two reasons. Overly aggressive mothers can cause an umbilical hernia. One of my girls will toss the puppies around the whelping box as she tries to chew through the cord. An umbilical hernia will look like a raised bump the size of a dime. It can be surgically repaired when the puppy is older with a stitch or two. Usually this is done when the puppy is being spayed or neutered.

The other reason is that they can chew it too close to the puppy's stomach. One girl chewed the cord right up to the puppy's stomach, and blood from the puppy began spurting all over the whelping box. If this happens, take a towel a press the area with firm but gentle pressure. Once it stops spurting blood, you can apply styptic powder to ensure it won't bleed again.

Some people recommend tying it off with dental floss or thread, but I have never found it to be necessary. If it was, dogs would not have survived as a species.

The remaining umbilical cord will dry up quickly and fall off sometime the following day.

Your Job as Delivery Progresses

You can dry the puppy with a towel, however mom will want to make sure her puppy is properly cleaned and dry with seemingly endless licking. Let her do her job.

Once mom is satisfied that her puppy is clean, you want to be sure it nurses shortly after arrival. The colostrum in the mother's first milk will provide many of the antibodies your puppy will need to stay healthy in its new environment.

Place the puppy near a teat, holding its head gently between your thumb and index finger. Then gently but firmly press the puppy's mouth against the teat, supporting the head with your hand. Some puppies take to it immediately, other struggle to get away. I am somewhat aggressive, and if they don't take to it, I will try to express some milk to encourage them to have their first meal. Nursing will stimulate contractions for the next puppy's delivery.

This is also a good time to give the mother some yogurt or ice cream. The calcium in these dairy products will help stimulate milk production.

As she goes into hard labor on subsequent deliveries, you will want to keep the puppies warm and dry. You can remove the puppies to a corner of the whelping box and place them under a heat lamp or just cover them loosely with a dry towel. A broken placenta can make the whelping box a very wet and bloody looking place.

Deliveries of litters can be accomplished in as short as 90 minutes, more typically it takes 3-6 hours, depending on the size of the litter. I have had one girl wait 7 hours between births, before delivering her last puppy.

While she is in labor, she will continue panting and breathing heavily. Once she has completed delivery, breathing will return to normal.

Following the Litter's Delivery

Once all of the puppies are born, clean up the whelping box and add fresh towels to it. You want to keep the room warm, to prevent chilled puppies. Puppies cannot regulate their temperatures at this age, and rely on warmth from each other and their mother as well as the ambient temperature. I try to keep the room temperature between 82 and 85 degrees with a space heater. Some people use heat lamps over one area of the whelping box, so that puppies can warm under the lamp as they require.

Once all of the puppies have enjoyed their first meal, you should weigh each puppy and keep a log of their weights. You want to weigh them once a day at least to be sure they are gaining weight. A puppy who does not gain weight everyday is in trouble. This is your best way to get an early clue to a distressed puppy.

If you have oxytocin on hand, a shot given after the last puppies arrival will help stimulate additional contractions to clear the uterus of any retained placentas. Once the puppies have all eaten, take her for a walk to potty and expel any remaining fluids or placentas. If your girl has fluffy pants, you may want to wash them off and towel dry her before returning her to the whelping box.

Walk her again 3 hours later, as the richness of placentas can give them upset stomachs. You can expect discharge for the next 2-3 weeks. This is normal. However if it is accompanied by a foul odor, its time to make a trip to the vet, as this indicates an infection. See a vet as soon as possible to get it under control quickly. A sick mother will mean a lot of work for you.

Now you can sit back and watch your puppies grow! Be sure the mother has plenty of fresh clean water, as this is essential to her milk supply. She will do most of the work for the next 3 weeks, you will just need to change bedding and handle the puppies to socialize them.

What a thorough article this is! Years ago I had a dog that delivered 10 puppies! I didn't know half of the things you describe here, but, fortunately, all of the puppies survived and thrived.

If there is such a thing as a midwife for dogs, you would be in high demand. Enjoyed and voted up and awesome.

Hi Writer Fox: Thanks for visiting! I don't know that I could handle the stress of being a puppy midwife. It is exhausting sitting up with them all night. Mine always want to start having babies at 4-5 in the morning.

Hi Colorfulone - Send your daughter on down next time we have a litter due! I could use a hand while I am napping. lol
