Calcule a data do parto da sua cadela e o cronograma da gravidez. A gestação canina dura aproximadamente 63 dias (58–68 dias) desde a concepção.
Calculadora de Gravidez de Cães
The dog pregnancy calculator estimates the whelping (birth) date based on the date of mating. Canine gestation typically lasts 63 days from ovulation, though puppies may arrive anywhere from day 58 to day 68.
If you know the mating date, add 63 days for the estimated whelping date. If you know the ovulation date (from progesterone testing), the estimate is more precise.
Regular veterinary care during pregnancy is essential. Your vet can confirm pregnancy with ultrasound at 25–28 days and X-ray at 45+ days to count puppies.
