Find out when your Yorkie is due by using this Yorkie Gestation Calendar.

Yorkie Gestation Calendar Calculator

It’s easy to use this Yorkie Gestation Calculator to determine an approximate whelping date for your dog.

Using the Yorkie Gestation Calendar (Calculator)

Calculate Based on Day Yorkie Was Bred

If all you know is the day your Yorkie was bred, you can use this calendar to get a fairly good idea of when your dog is due to whelp. Using the day of breeding as your starting point, you will be able to plan for the arrival of your new puppies.

Technically, you want to count 63 days from ovulation to determine her estimated whelping date. If you don’t know what day she ovulated, you can use the breeding date to get a fairly reliable whelping date to work with.

For a natural breeding, generally a dog will allow herself to be bred during a 3-4 day window – so the time of breeding and the time of ovulation will be somewhat close. However, sometimes the female will be receptive to breeding over a period of 7-11 days…making the breeding date a less reliable starting point.

In light of determining the whelping date of your Yorkie based on breeding date, just recognize that it might be a few days off because the gestation date should be based on ovulation date.

Using the Calendar

There are 2 Gestation Calendars below. One for a breeding date between January and June and one for a breeding date between July and December.

Simply find the date your Yorkshire Terrier was bred on our chart (the left column). The date in the column directly to the right is your estimated whelping date.

Calculate Based on Ovulation Day

For most canines, the gestation period is 63 days. This gestation period is calculated not from time of breeding, but time of ovulation. So if you desire a more accurate whelping date, you should use your dog’s date of ovulation – not breeding date.

When your dog goes into heat, you can work with a vet to determine not only when she ovulates, but also the best time for breeding. To do this, vets can perform a Progesterone Test. The progesterone test is a blood test used to measure progesterone. As the progesterone rises, the vet can determine when an LH (Luteinizing hormone) surge occurs. Ovulation will occur about 24-48 hours after this LH surge. Ovulation should be considered Day 0. After you establish Day 0, count 63 days after this date to find your estimated whelping date. It should be fairly accurate.
