Dog Pregnancy Signs, Timeline, and When to Worry: A Complete Guide

Unlike humans, dogs do not have a simple home test for pregnancy. The earliest reliable confirmation is an ultrasound at 25-30 days after mating. But there are signs you can watch for even before that. - Days 1-14: No visible signs. Fertilisation and implantation happen silently. - Days 14-21: Some dogs show mild appetite changes or slight nipple enlargement. - Days 21-28: Morning sickness is possible — mild vomiting, reduced appetite. Nipples become more prominent and pink. - Days 28-35: Visible belly growth begins. Appetite increases. This is when most pet parents first suspect pregnancy. - Days 35-49: Significant weight gain. Belly is noticeably larger. Puppies can be felt by a vet on palpation. - Days 49-63: Nesting behaviour — seeking quiet, enclosed spaces. Mammary glands fill with milk. Body temperature drops 1-2 degrees about 24 hours before labour.

- First 4 weeks: Normal adult food, normal portions. Do not overfeed early — excess weight makes delivery harder. - Weeks 5-6: Increase food by 25%. Switch to puppy food or a high-calorie diet — pregnant dogs need the extra protein and calcium. - Weeks 7-9: Increase food by 50%. Feed 3-4 smaller meals instead of 2 large ones — the growing puppies compress the stomach. - Always provide fresh water. Dehydration during pregnancy is dangerous.

- Green or black vaginal discharge before any puppy is born - More than 2 hours of strong contractions with no puppy delivered - More than 4 hours between puppies - Extreme lethargy or collapse - Bloody discharge that does not stop - Fever above 39.5°C during pregnancy - Vomiting or diarrhea that lasts more than 24 hours - The dog has been pregnant for more than 65 days with no signs of labour

Set up a whelping box 7-10 days before the due date. Use a large cardboard box or plastic container lined with clean towels. Place it in a quiet, warm corner away from household traffic. The mother needs to feel safe. Keep the room temperature around 29-32°C for the first week after birth — newborn puppies cannot regulate their own body temperature.

Most dogs deliver without human intervention. But stay nearby and watch. - Each puppy arrives in an amniotic sac. The mother should tear it open and lick the puppy to stimulate breathing. - If she does not tear the sac within 30 seconds, you need to do it gently. - The umbilical cord is usually chewed by the mother. If not, tie it with clean thread about 2 cm from the puppy's body and cut with sterile scissors. - Count the placentas. There should be one per puppy. A retained placenta causes infection.

The mother will be exhausted and hungry. Offer warm food and water. Watch for signs of infection — fever, foul-smelling discharge, refusal to eat, or neglecting the puppies. Mastitis (infected mammary glands) is common — look for hot, hard, painful nipples.

In India, many pregnancies are unplanned — especially with Indie dogs. If you are caring for a pregnant stray, the same principles apply. Provide nutrition, a safe delivery space, and watch for complications. Consider spaying after the puppies are weaned (6-8 weeks) to prevent future litters.

Log the mating date, track symptoms week by week, and set reminders for vet check-ups and dietary changes. When delivery day approaches, Omelo can help you assess whether a symptom is normal or needs urgent attention — especially at 2 AM when the vet clinic is closed.
