The average dog pregnancy lasts approximately 63 days from the date of mating. This can vary slightly by breed and individual dog, but 63 days is the standard gestation period used for calculation purposes.
The calculator uses the following formula:
Where:
Explanation: The calculator determines how many days have passed since mating, calculates the current week of pregnancy, and estimates how many days remain until delivery.
Details: Tracking your dog's pregnancy week by week is crucial for proper prenatal care, nutrition planning, and preparing for whelping. It helps you anticipate important milestones and know when to expect the puppies.
Tips: Enter the exact mating date and either today's date or any date you want to check. The calculator will show you the current week of pregnancy, days passed, days remaining, and estimated due date.
Q1: Is 63 days exact for all dogs?
A: While 63 days is the average, gestation can range from 58-68 days depending on the breed and individual dog.
Q2: When should I take my dog to the vet during pregnancy?
A: Schedule a vet visit within the first 3 weeks after mating to confirm pregnancy, and again around day 45 for ultrasound or X-ray to count puppies.
Q3: What are the signs of approaching labor?
A: Nesting behavior, temperature drop (below 100°F), loss of appetite, and restlessness typically occur 24-48 hours before labor.
Q4: How many puppies can I expect?
A: Litter size varies by breed - small breeds typically have 1-4 puppies, medium breeds 5-8, and large breeds can have 8-12 or more.
Q5: When should I set up the whelping box?
A: Prepare the whelping area by week 7 (around day 49) so your dog has time to become comfortable with it before delivery.
