Dog Pregnancy — Week-by-Week Guide for Owners

How Long Are Dogs Pregnant?

Dog pregnancy (also called gestation) typically lasts about 63 days, or roughly nine weeks. That said, healthy pregnancies can range from 58 to 68 days depending on the breed, litter size, and the timing of conception relative to ovulation. Smaller breeds sometimes deliver a day or two earlier, while larger breeds may go slightly longer — but if your dog reaches day 70 without signs of labor, contact your veterinarian immediately.

Because dog pregnancy moves so quickly compared to human pregnancy, a lot happens in a very short time. Understanding each stage helps you provide the right nutrition, veterinary care, and emotional support exactly when your dog needs it.

Dog Pregnancy Symptoms Week by Week

One of the trickiest things about early dog pregnancy is that there aren't many visible signs at first. Your dog may act completely normal for the first few weeks. But behind the scenes, incredible things are happening. Here's a detailed look at what's going on each week — and what you, as the owner, should be doing.

Week 1 (Days 1–7): Fertilization

After mating, sperm travels to the eggs and fertilization occurs. The fertilized eggs begin dividing as they travel toward the uterine horns. At this stage, there are no outward symptoms at all. Your dog will behave normally, eat normally, and show no physical changes.

• What to do: Continue your dog's normal diet and exercise routine.
• Avoid any unnecessary medications, vaccinations, or flea treatments unless approved by your vet.
• If the breeding was intentional, log the date for due-date calculations.

Week 2 (Days 8–14): Cell Division and Travel

The embryos continue to divide and travel down the fallopian tubes toward the uterus. Still no visible changes in your dog. Some dogs may show a very subtle decrease in appetite or slight mood changes, but most owners won't notice anything.

Week 3 (Days 15–21): Implantation

This is a critical week. The embryos implant into the uterine wall, and the placenta begins forming. Some dogs experience a brief loss of appetite or mild morning sickness — yes, dogs can get morning sickness too! You may also notice your dog becoming slightly more affectionate or quieter than usual.

Week 4 (Days 22–28): First Vet Confirmation

This is when things get real. By day 25–28, your vet can confirm pregnancy via ultrasound. You may notice slight clear vaginal discharge, swelling of the nipples, and possible mood or appetite changes. The embryos are about the size of walnuts and are developing their spinal cords, eyes, and faces.

• Schedule a vet ultrasound between days 25–30 to confirm pregnancy and check embryo health.
• Begin transitioning to a high-quality puppy food or pregnancy-specific diet (your vet will guide you).
• Watch for signs of morning sickness — offer smaller, more frequent meals if needed.

Weeks 5–6: The Growth Spurt Begins

Week 5 (Days 29–35): Organ Development

The fetuses are now developing toes, claws, whiskers, and individual markings. Their weight increases rapidly, and mom's belly will start to visibly expand. Her appetite should return — and then some. Nipple darkening becomes more obvious, and she may begin to gain noticeable weight.

Week 6 (Days 36–42): Puppies Take Shape

The puppies' skeletons are calcifying, which means they'll now be visible on an X-ray (though most vets wait until week 7–8 for the most accurate puppy count). Your dog's belly is clearly enlarged, and she may start showing nesting behaviors — rearranging blankets, seeking quiet spots, or becoming more protective of her space.

• Increase meal portions by 25–50% and consider feeding 3 smaller meals instead of 2 larger ones.
• Keep exercise gentle — walks are great; avoid jumping, rough play, and strenuous activity.
• Begin gathering whelping supplies (more on that below).

Weeks 7–8: Preparing for Whelping Day

Week 7 (Days 43–49): Rapid Growth

The puppies are growing fast, and your dog may start to look quite large and uncomfortable. You might actually be able to see or feel the puppies moving if you place your hand gently on her abdomen. She may shed fur from her belly as her body prepares for nursing. Her appetite may be huge — keep offering nutrient-dense food in frequent small meals.

Week 8 (Days 50–56): The Home Stretch

Puppy movement is clearly visible. Your vet may recommend an X-ray around days 50–55 to get an accurate puppy count — this is incredibly helpful so you know when delivery is complete. Mom may become restless, pant more, and lose interest in food as her due date approaches. Now is the time to set up your whelping box and make sure everything is ready.

Week 9: Labor and Delivery

Week 9 (days 57–63+) is when the magic happens. In the days before labor, your dog's body temperature will drop from a normal ~101.5°F to below 99°F — this drop usually signals labor will begin within 24 hours. She may refuse food entirely, become very restless, pant heavily, or nest obsessively.

Labor happens in three stages:

1. Stage 1 — Early labor (6–12 hours): Restlessness, panting, shivering, nesting. Cervix dilates. No visible contractions yet.
2. Stage 2 — Active labor and delivery: Visible contractions begin, and puppies are born one at a time, typically 30–60 minutes apart. Mom will clean each puppy and chew through the umbilical cord.
3. Stage 3 — Placenta delivery: A placenta is delivered after each puppy. Count them — a retained placenta can cause serious infection.

Pregnant Dog Care: Nutrition, Exercise, and Vet Visits

Taking care of a pregnant dog isn't complicated, but it does require some intentional adjustments. Think of it as giving your girl the VIP treatment she deserves while she's growing an entire litter of tiny lives.

Nutrition

• Weeks 1–4: Feed her normal high-quality adult food. No extra calories needed yet.
• Weeks 5–6: Transition to puppy food or a vet-recommended pregnancy diet. Increase portions by 25–50%.
• Weeks 7–9: She may need up to 50–75% more food than her pre-pregnancy intake. Offer 3–4 smaller meals per day, as her growing uterus compresses her stomach.
• Always ensure fresh water is available — pregnant dogs drink significantly more.
• Avoid calcium supplements unless specifically directed by your vet (excess calcium can cause dangerous eclampsia).

Exercise

Regular, moderate exercise is great for pregnant dogs — it supports muscle tone, healthy weight, and mental well-being. Gentle daily walks are ideal. However, avoid strenuous exercise, agility training, rough play with other dogs, and any activity that could result in a fall or blow to the abdomen, especially after week 4.

Vet Visits

• Day 25–30: Ultrasound to confirm pregnancy and assess embryo viability.
• Day 45: Mid-pregnancy check-up; discuss whelping plan and any concerns.
• Day 50–55: X-ray for accurate puppy count.
• Pre-labor: Have your vet's emergency number saved and know the after-hours protocol.

Whelping Preparation Checklist

Being prepared for delivery day can make the difference between a smooth, joyful experience and a panicked scramble. Here's everything you'll want to have ready by week 7:

• Whelping box with clean, washable bedding
• Heat lamp or heating pad for puppies (set to one side so puppies can move away if too warm)
• Clean towels and washcloths
• Bulb syringe for clearing puppy airways
• Unwaxed dental floss and blunt scissors (to tie/cut umbilical cords if mom doesn't)
• Digital thermometer (to track mom's temperature drop)
• Kitchen scale for weighing puppies daily
• Puppy milk replacer (in case of nursing problems)
• Vet's phone number and emergency clinic contact
• Notebook to log delivery times, puppy weights, and placenta count

After the Puppies Arrive: The First 48 Hours

Once all the puppies have arrived safely, your job shifts to quiet observation. Make sure each puppy is nursing within the first 1–2 hours — that first milk (colostrum) is packed with essential antibodies. Weigh each puppy and record it; healthy puppies should gain weight every single day.

Keep the whelping area warm (around 85°F for the first week), clean, and quiet. Limit visitors, especially in the first few days — mom may become stressed or protective. Watch her for signs of complications like excessive bleeding, foul-smelling discharge, fever, or refusal to nurse, and contact your vet if anything seems off.
