How do you calculate dog pregnancy?

You can't accurately calculate dog pregnancy like you would with humans. Here's why:

* Gestation period varies: A dog's gestation period is roughly 58-67 days, but it can vary depending on the breed, individual dog, and even the number of puppies in the litter.

* No reliable "due date" calculation: Unlike human pregnancy, there's no specific date that can be accurately predicted based on the mating date.

* Ultrasound is the most reliable indicator: Veterinarians use ultrasound to confirm pregnancy and estimate the due date based on the size and development of the puppies.

Here's how to track your dog's pregnancy:

1. Know the mating date: Keep detailed records of the mating dates if your dog was bred.

2. Observe for early signs: Around 2-3 weeks after mating, your dog may show signs of pregnancy, including:

* Nipple enlargement and darkening

* Increased appetite

* Vomiting

* Weight gain

* Behavioral changes like nesting

3. Visit your veterinarian: A veterinarian can confirm pregnancy through a physical exam and ultrasound.

4. Monitor for signs of labor: As the due date approaches, monitor for signs of labor, which include:

* Restlessness

* Panting

* Nesting behavior

* Frequent urination

* Discharge from the vulva

Remember: A veterinarian is your best resource for tracking your dog's pregnancy and ensuring a safe and healthy outcome for both the mother and the puppies.
