how many days is a dog pregnant
The short answer is 63 days on average, but the real range runs from 58 to 68 days, depending on exactly when ovulation happened relative to the mating date. This calculator uses that same range to project a due-date window from the mating date you enter, then narrows it further once you pick the female's size.
Very small breeds trend toward the lower end of the 58-63 day range.
Large/giant breeds trend toward the upper end of the 60-68 day range.
On average 63 days from mating, within a range of 58 to 68 days according to the AKC and VCA Animal Hospitals. The actual duration from ovulation is more consistent (~63 days); the variation mostly comes from uncertainty about the exact ovulation day.
Within the documented range (up to 68 days from mating), it usually is not. If it goes past that point with no signs of labor, contact your vet for an evaluation.
A vet can monitor ovulation through blood progesterone testing during heat, the most precise method for narrowing down the likely due date.
Not with precision. Without monitoring ovulation through a progesterone test, the best available estimate is the range of days from mating, 58 to 68 days, since the gap between mating and actual ovulation can vary by several days between dogs.
No. Unlike dogs, which range from toy to giant breeds, domestic cats vary far less in size between breeds, so the feline pregnancy range (61 to 65 days) is not adjusted by size the way the canine range is.
Veterinary notice: this calculator is educational and does not replace care from a licensed veterinarian. Confirm the pregnancy and monitor the female with appropriate exams (ultrasound, X-ray) and regular checkups.
