How Long are Yorkies Pregnant? Litter Size and Early Signs Guide

How long are Yorkies pregnant? This is a question that has several answers, reason being is that labor can be induced by several factors and here are the most prevalent ones you need to watch out for.

If you suspect that your female Yorkie has mated, there are a number of important facts you need to be aware of in a canine pregnancy to ensure a smooth delivery.

How Long are Yorkshire Terriers Pregnant for?

It is possible for a Yorkie to become pregnant the very first time she mates.

The average gestation period (i.e. pregnancy period) for Yorkies, generally lasts between 58 to 68 days with around 63 days being the average.

If by day 67, your Yorkie has still not delivered, it’s a good idea to call your veterinarian.

The reason for such a variance in days can be boiled down to the size of the dog.

Toy breeds generally carry their pups somewhat longer than larger breeds. Both the size of the mother and litter size play a key role in how long your Yorkie is pregnant for.

Your breeder may also be of help since pregnancy lengths run in the family. Try and find out how long her mother’s pregnancy lasted for.

Finally a canine pregnancy calendar can also be useful to pinpoint your Yorkie’s approximate arrival due date. This works if you have the actual date your Yorkie was bred. Failing that, try to recall when she was last in heat, and simply count the middle of that heat cycle as the most probable time of breeding.
