Complete Guide to Dog Pregnancy: Care, Signs, and Puppy Preparation
Everything you need to know about canine pregnancy from conception to whelping

Understanding Dog Pregnancy: A Comprehensive Guide
Welcoming a new litter of puppies into the world is incredibly rewarding, but dog pregnancies can be confusing, stressful, time-consuming, and costly. If you’re considering breeding your dog, there’s crucial information you need to know to ensure the health and well-being of both the mother and her puppies. This guide covers everything from recognizing pregnancy signs to caring for your pregnant dog and preparing for the arrival of puppies.
Before Breeding: Important Considerations
Before deciding to breed your dog, you should familiarize yourself with your breed’s standard and individual breed health test recommendations. Responsible breeding requires understanding the significant responsibilities involved in raising healthy, well-socialized puppies.
Pre-Breeding Health Checks
Taking your dog to the veterinarian for a comprehensive pre-breeding examination is essential. During this visit, your veterinarian will:
- Ensure your dog is up-to-date on all necessary vaccinations
- Conduct a thorough physical examination to assess overall health
- Potentially recommend a fecal exam to check for intestinal parasites
- Discuss appropriate deworming protocols before breeding
- Evaluate for any mechanical or anatomical concerns that could complicate pregnancy or delivery
Canine Gestation: Timeline and Duration
Dogs are pregnant for approximately 62-64 days, or about two months. However, predicting the exact timing of delivery can be challenging. Understanding the canine gestation timeline helps you prepare appropriately and monitor your dog’s progress throughout pregnancy.
Signs of Pregnancy in Dogs
Recognizing pregnancy signs early allows you to provide appropriate care from the start. Common indicators that your dog might be pregnant include:
- Increased appetite and weight gain
- Enlarged nipples
- Changes in behavior, including possible lethargy or nesting
- A slightly swollen abdomen (particularly noticeable in the later stages)
It’s important to note that false pregnancies can occur in dogs, presenting similar symptoms. Only a veterinarian can confirm pregnancy through proper examination techniques.
Veterinary Care During Pregnancy
Regular veterinary visits are crucial for monitoring your dog’s pregnancy and ensuring both mother and puppies remain healthy throughout gestation.
Pregnancy Confirmation
A veterinarian can usually confirm pregnancy through:
- Abdominal palpation at around 28 days
- Ultrasound examination, which can detect puppies earlier than x-rays
- X-rays, which are typically performed later in pregnancy to count the number of puppies
Ongoing Veterinary Support
During your prenatal veterinary visits, discuss a plan for emergency situations, particularly as the whelping date approaches. Establish contact information for emergency veterinary services and create a clear plan with family members and pet sitters about what to do if complications arise.
Nutrition for Pregnant Dogs
Proper nutrition is vital for supporting your pregnant dog and her developing puppies. Dietary needs change throughout pregnancy, requiring careful attention and adjustments.
First Half of Pregnancy
If your dog is at a healthy weight and consuming a high-quality, well-balanced diet, minimal changes are typically needed during the first half of pregnancy. Continue feeding her regular diet as usual, maintaining consistent caloric intake similar to her adult maintenance requirements.
Second Half of Pregnancy
As your dog enters the last five weeks of pregnancy, dietary adjustments become necessary:
- Gradually increase food intake as her body weight increases
- By whelping time, she may need 35-50% more food than usual
- Switch to smaller, more frequent meals to reduce discomfort caused by her compressed stomach
- Ensure continued access to high-quality, nutritionally complete dog food
Supplements and Special Considerations
A high-quality, balanced diet should provide all necessary nutrients. However, some breeders advocate supplementation with protein sources such as:
- Evaporated milk
- Eggs
- Meat
- Liver
If supplements are used, they should never represent more than 10% of the bitch’s daily food intake. Always consult with your veterinarian before adding supplements to your pregnant dog’s diet.
Exercise and Activity During Pregnancy
Maintaining appropriate exercise is important for keeping your pregnant dog healthy and prepared for the physical demands of giving birth.
Exercise Guidelines
Regular, moderate exercise helps maintain muscle tone and overall fitness, which is beneficial for labor. Consider these guidelines:
- Continue regular walking throughout pregnancy
- As pregnancy progresses, opt for shorter, more frequent walks (three to five short walks daily)
- Avoid rigorous activities, intense training, and physically demanding obedience work
- Be mindful of temperature and terrain (avoid steep hikes and exercise in extreme weather)
- Allow for rest periods and never force exercise if your dog seems tired
Parasite Control During Pregnancy
Controlling parasites is essential for protecting both the mother and her developing puppies.
Deworming Protocol
Current veterinary recommendations suggest deworming pregnant dogs with appropriate medication (such as Fenbendazole) starting in the third trimester (around day 40 of gestation) and continuing until approximately 14 days after whelping. This protocol significantly reduces roundworm and hookworm transmission to newborn puppies, allowing them to grow and thrive optimally.
Preparing for Whelping
As your dog’s due date approaches, proper preparation becomes essential for ensuring a smooth whelping process.
Creating a Whelping Area
Set up a comfortable, quiet whelping area at least two weeks before the expected due date. This should include:
- A whelping box large enough for the mother to stretch out comfortably
- Low sides that allow the mother to enter and exit easily
- A protected, warm environment away from household traffic
- Clean, comfortable bedding that can be easily changed
Introduce your dog to the whelping box at least five days before her expected delivery date so she can become comfortable and adjusted to the space before the puppies arrive.
Whelping Supplies
Gather necessary supplies well in advance, including:
- Clean towels and washcloths
- Heat source for puppies (heating pad or heat lamp)
- Thermometer to monitor mother’s temperature
- Sterilized scissors for cutting umbilical cords if necessary
- Dental floss or thread for tying umbilical cords if needed
- Iodine solution for umbilical cord treatment
- Scale for weighing puppies
- Notebook for recording birth times and weights
Recognizing Labor Signs
Knowing the signs of impending labor helps you prepare for delivery and recognize potential complications requiring veterinary assistance.
Pre-Labor Indicators
Watch for these signs that labor may be approaching:
- Drop in body temperature below 100°F (normal is 101-102.5°F)
- Restlessness and nesting behavior
- Decreased appetite
- Milk production beginning
Emergency Preparedness
Despite the best preparation, complications can arise during pregnancy or whelping. Being prepared for emergencies is crucial for the safety of both mother and puppies.
When to Contact Your Veterinarian
Seek immediate veterinary assistance if you observe:
- Strong contractions for more than 30-60 minutes without producing a puppy
- More than 2 hours between puppies when you know there are more to come
- Excessive bleeding or foul-smelling discharge
- Signs of extreme pain or distress
- Weakness, lethargy, or collapse
After Whelping: Caring for Mother and Puppies
Once the puppies have arrived, proper care continues to be essential for both mother and newborns.
Maternal Care
The mother dog’s needs after whelping include:
- Continued high-quality nutrition with increased caloric intake to support lactation
- Fresh water at all times
- Quiet, comfortable environment with minimal disturbances
- Monitoring for signs of complications such as mastitis or eclampsia
- Gradual return to normal exercise as appropriate
Puppy Monitoring
Newborn puppies require careful observation. Monitor for:
- Nursing success and weight gain
- Appropriate warmth and temperature
- Normal elimination with maternal stimulation
- Any signs of distress or illness requiring veterinary attention
