The dam should be put into a whelping box as labor begins. This can be a cardboard box with one side cut out in order to "flap down". Another option is a canine bed (a Perla bed without the cushion, but lined with soft cloths can work well). If the sire or any male dogs are in the home, they should be removed and safely separated to a different room.
Having lots of layers of clean newspaper or small sections of sheets lining the whelping box will allow you to keep pulling soiled and soaked sheets away, leaving a new layer of clean paper or sheets.
The puppies may come out one right consecutively or there may be a time span of up to 2 hours in between the puppies emerging. Each will be born encased in its own amniotic sac. In some cases, this rips open as it passes through the birth canal, but more often than not, it remains intact and will be gently torn open by the dam. She will also bite the umbilical cord and lick the puppies to clean away mucus and stimulate breathing.
Once all the pups are born, it is perfectly natural for the dam to ingest the umbilical cords, amniotic sac, placenta and other tissues.
Any puppies that do not find their way to her tummy to nurse should be carefully moved there. Keep an eye out for a newborn puppy
that is very small and being pushed out of the way by larger littermates. All puppies will need to be closely monitored to make sure that they are adequately nursing. If not, bottle feeding may need to be done as hypoglycemia can quickly set in
Cleaning bedding should be put down and a heating pad, set on "warm" should be put under the blanket.
Care for the Female Yorkie Afterward
The dam can be given a warm sponge bath her clean and settled down into clean, soft blankets, allowing her to rest with her litter. While she may not be immediately hungry, water and food should be available at all times.
There may be some light discharge for up to a week. This should be any color ranging from pink to red or even a bit brown. If the discharge is excessive or if it is an odd color (green or black), contact the vet right away.
The temperature in the whelping box should be 85 degrees Fahrenheit for the 1st week and 82 degrees Fahrenheit the 2nd and 3rd week. Take care that there are no cool or cold drafts.
