How long is a dog pregnant?
A normal dog pregnancy lasts between 58 and 68 days, with the average being 63 days from the time of ovulation. Because mating can happen over several days and sperm can live inside the female for a few days, calculating the exact due date from mating alone gives a window rather than a single specific day.
Does breed size affect the due date?
Yes, slightly. Smaller breeds (Toy and Small) often deliver a few days earlier than larger breeds, sometimes around day 61. Large and giant breeds tend to go closer to day 63 or even a bit longer.
Signs your dog is pregnant
- Week 3-4: Morning sickness, decreased appetite, slight lethargy.
- Week 4-5: Weight gain, enlarged and darker nipples.
- Week 6+: Noticeable belly growth, increased appetite, nesting behavior.
When to see a vet
You should schedule a veterinary visit around day 28-35 of the pregnancy. At this point, the vet can confirm the pregnancy via ultrasound or palpation. Around day 45-55, an X-ray can be done to count the number of puppies, which is crucial for knowing when the mother has finished delivering.
