Expecting Puppies? A Complete Guide to Mother Dog Care

How Can You Tell If a Dog Is Pregnant?

During the first 2–3 weeks following fertilization, no external signs are visible. Around week 3, however, hormonal shifts may trigger a brief spell of mild loss of appetite, nausea, and lethargy. From week 4 onward, the teats begin to swell and turn pink, and the dog's behavior changes: many females become more affectionate and clingy, or conversely, seek more rest and retreat to a quiet space.

When Does a Pregnant Dog’s Belly Begin to Grow?

A pregnant dog's belly typically starts to thicken and round out noticeably around weeks 5 to 6. Because fetuses gain nearly 75% of their total weight during the final 3 weeks, abdominal growth becomes dramatic near the end of gestation. In the final days, puppy movements can often be seen with the naked eye through the abdominal wall.

How Can Pregnancy Be Confirmed for Certain?

Only a veterinary examination can definitively confirm pregnancy:

• Ultrasound (from Day 28): Detects fetal heartbeats, confirming both pregnancy and fetal viability.
• Relaxin Hormone Test (Days 25–30): A blood test that detects a pregnancy-specific hormone.
• Veterinary Palpation (Days 28–35): An experienced veterinarian can feel the walnut-sized gestational sacs in the uterus.
• X-ray / Radiography (from Day 50–55): Once fetal skeletons calcify, an X-ray is the most reliable way to determine the exact litter count. Knowing this number is essential for recognizing when labor has fully concluded.

False Pregnancy (Pseudopregnancy)

False pregnancy occurs in non-pregnant females about 6–8 weeks following estrus (heat) due to a natural drop in progesterone levels. The dog genuinely "believes" she is pregnant: she may build a nest, mother plush toys, experience swollen breasts, and even produce milk. If symptoms are severe, veterinary treatment (hormonal therapy or anti-inflammatories) is necessary, as stagnant milk in the glands can lead to mastitis.

How Long Does Gestation Last and What Happens in Each Stage?

Canine gestation lasts an average of 63 days (ranging between 58 and 68 days).

• Weeks 1–3: Fertilized eggs implant into the uterine wall. Cells divide rapidly, though the embryos remain grain-of-sand sized.
• Weeks 4–6: Internal organs form, and puppies take shape. By the end of week 6, the fetuses are fully formed tiny puppies.
• Weeks 7–9: Bone calcification completes, hair coats develop, and growth accelerates rapidly. Lactation (milk production) begins.

How Many Puppies Can a Dog Have?

Litter size depends heavily on breed, body size, age, and overall maternal health.

• Small breeds (e.g., Chihuahua, Yorkshire Terrier) typically deliver 1 to 4 puppies.
• Medium and large breeds (e.g., Retrievers, German Shepherds) average 6 to 10 puppies, while giant breeds can easily produce litters of 12 to 15.

Litter size depends heavily on breed, body size, the mother's age, and overall health.

Feeding and Nutrition for a Pregnant Dog

Do not increase food portions during the first 4–5 weeks of pregnancy, as excess weight makes labor more difficult. From week 5 onward—when fetal growth accelerates—gradually transition to a high-protein, high-fat puppy food or a nutrient-dense cooked diet. Increase daily rations by 10–15% each week, dividing the daily total into 3–4 small meals.

Should You Give Vitamins and Supplements?

• Strict Calcium Ban During Gestation: Never administer calcium supplements before whelping! Artificial calcium supplementation suppresses the dog's natural calcium-mobilization mechanism, which can cause life-threatening eclampsia (milk fever) during lactation.
• Neurological Support: Omega-3 fatty acids (DHA) and folic acid promote healthy brain and nervous system development in the puppies.
• Liquid Liver Support & Detoxification: During preconception preparation and post-whelping/C-section recovery, the dam's liver undergoes heavy strain processing medications, hormones, and metabolic waste. Because forcing pills on an anxious or inappetent dog causes significant stress, concentrated, palatable liquid liver drops offer an ideal solution. A few drops added to her food discreetly support liver detoxification and recovery.

Additional Precautions During Pregnancy

Avoid strenuous physical activity and stress, but maintain gentle, regular walks to preserve muscle tone. Deworming must be conducted using products specifically approved by your veterinarian as safe for pregnant dogs.

Seek immediate veterinary attention if you notice: foul-smelling or bloody vaginal discharge, high fever, prolonged loss of appetite, or abdominal cramping/pain.

Preparing for the Arrival of the Puppies

During week 8, set up a whelping box in a quiet, warm, draft-free room. Line it with clean, easily replaceable sheets or whelping pads, and ensure a heat source is available (such as an infrared heating lamp), as newborn puppies cannot regulate their own body temperature.

How Can You Tell That Whelping Is Approaching?

Temperature Drop: 12 to 24 hours before labor begins, the mother’s rectal body temperature drops by at least 1 °C (often falling below 37 °C / 98.6 °F).

Behavioral Changes: Restlessness, frantic nesting/scratching, panting, shivering, and total refusal of food.

The duration of whelping varies based on the individual dog and the size of the litter.

How Fast Does Whelping Progress?

The duration of whelping varies based on the individual dog and litter size, but the process breaks down into 3 main stages:

• Stage 1: Preparatory Stage (6–12 hours, up to 24 hours):

The cervix dilates. The mother is restless, pants, shivers, and refuses food. Visible abdominal contractions are not yet present.

• Stage 2: Delivery of Puppies (3–12 hours):
• The first puppy is typically born after 30–60 minutes of active straining.
• Subsequent puppies usually follow at intervals of 15 to 60 minutes.
• It is normal for the mother to take a longer rest (1–2 hours) between puppies, provided she is calm and not actively straining.
• Stage 3: Passing the Placenta:

A placenta is passed either along with each puppy or shortly afterward.

When to Call the Vet Immediately:

• Strong, continuous straining for more than 30–45 minutes without producing a puppy.
• More than 2 hours have passed between puppies while the dam continues to have contractions.
• Dark green or black vaginal discharge appears before the first puppy is born.
• Labor appears stalled, or the dam becomes visibly exhausted or weak.

The Nursing Period and Potential Pitfalls

By weeks 3–4 of lactation, the mother's energy requirements increase to 3 to 4 times her normal maintenance level. Provide unlimited access to high-calorie food and fresh water.

Key Risks During Lactation:

• Eclampsia (Milk Fever): A life-threatening emergency caused by acute calcium deficiency. Symptoms include a stiff gait, panting, muscle spasms, and fever. Requires immediate emergency veterinary intervention!
• Mastitis: Hot, hard, swollen, purple, or painful mammary glands with bloody or purulent milk.
• Metritis (Uterine Infection): Foul-smelling dark vaginal discharge, fever, and neglect of the puppies.

Accidental Pregnancy: What to Do?

If a female dog accidentally escapes while in heat or an unplanned mating occurs, contact your veterinarian immediately. The vet can confirm pregnancy via ultrasound and hormone testing. In the early stages, safe medical procedures (surgical spaying or pregnancy-termination injections) can prevent an unwanted litter. If you choose to carry the pregnancy to term, proper nutritional support and maternal care preparations must begin without delay.

Be a Responsible Owner: Spay If You Don't Plan to Breed!

While bringing puppies into the world is a wonderful experience, animal shelters are filled with homeless dogs. Raising a litter requires significant financial, physical, and time commitments, and carries real health risks for the mother.

Unless you are a registered, responsible breeder, spaying is the most compassionate choice you can make. Spaying not only prevents unwanted pregnancies, but also protects the female from severe, life-threatening conditions such as pyometra (uterine infection) and mammary tumors.
