Canine pregnancy is commonly estimated at about 63 days from ovulation, but timing from mating may be less precise.

Watch for warning signs
Seek veterinary help for severe pain, weakness, unusual discharge, prolonged straining, or any concern about the mother or puppies.
Frequently asked questions
How long are dogs usually pregnant?
A common estimate is around 63 days from ovulation. Counting from mating can produce a wider range because mating and conception may not happen on the same day.
Why does the calculator show a date range?
Pregnancy length varies, and the exact conception date may be uncertain. The displayed window is a practical planning estimate rather than a guaranteed delivery period.
Can this calculator confirm pregnancy?
No. Pregnancy confirmation and litter assessment require veterinary evaluation, which may include examination, ultrasound, or other tests.
When should I contact a veterinarian?
Arrange routine prenatal guidance early, and seek urgent help for concerning symptoms, overdue pregnancy, prolonged labor, or distress.
