Conception & Early Growth
Fertilization occurs in the oviducts. You may notice mild morning sickness. Maintain normal exercise but avoid intense training.

Embryos Implanted
The most critical stage. Puppies can be felt by a vet via palpation. Nipple development becomes visible.
- Vet confirmation
- Clear discharge is normal
Whelping Is Near
Puppies are fully formed. Mother becomes restless and starts "nesting". Monitor rectal temperature for drop.

How Long Are Dogs Pregnant?
The average gestation period for dogs is 63 days (about 9 weeks), though it can vary from 58 to 68 days.
Variance often depends on the dog's breed and size. Smaller breeds often have slightly shorter pregnancies, while larger dogs may carry for the full term or slightly longer.
Pro Tip:
Calculating from the date of ovulation is more accurate than mating date, as sperm can live inside the female for several days.
When To Contact A Vet
While dog pregnancy is a natural process, there are signs that require immediate professional attention to ensure the safety of both mother and puppies.
Abnormal Discharge
Bloody or foul-smelling discharge before the due date.
Overdue Pregnancy
