Yorkie Pregnancy Calculator

How long is a Yorkie pregnancy? Yorkshire Terrier gestation averages 63 days (about 9 weeks) from the date of breeding. The normal range is 58 to 68 days, so a due date is an estimate—your vet can help confirm timing and check that your Yorkie and her litter are healthy as the due date approaches.

Knowing the expected due date helps you prepare: set up a whelping area, have supplies on hand, and schedule a vet visit if you haven’t already. Early pregnancy (weeks 1–3) shows few visible signs; by week 4 an ultrasound can confirm pregnancy, and by the second half of gestation your Yorkie’s belly and appetite will increase. In the final week she may nest, become restless, or lose her appetite as labor nears.

Use the calculator below to enter your Yorkie’s breeding date and see the estimated due date plus a week-by-week gestation guide. This tool is for planning only—always work with your vet for pregnancy care, especially in small breeds like Yorkies, where litter size and delivery can need extra attention.

If you’re considering breeding your Yorkie, choose a mate from health-tested lines and work with responsible breeders who prioritize temperament and breed standards. Our breeder directory can help you find vetted Yorkshire Terrier breeders and learn more about responsible breeding.
