Worth knowing

  • Brachycephalic puppies may have difficulty fitting through the birth canal
  • Under-5-lb dams have significantly higher C-section rates

Brachycephalic breed with moderate C-section risk. Smaller Shih Tzus have higher whelping complications.

Moderate risk, individual answers

Smaller Shih Tzus tend to have more whelping complications. Your vet may suggest an X-ray to check puppy size and decide whether to plan surgery.

Coat and cleanliness

Trim the long hair around the belly and rear before whelping so it stays clean and puppies can find the nipples easily. Ask your groomer or vet to do this if you are unsure.

Keep breathing easy

As a flat-faced breed she can struggle in heat or when stressed. Keep the room cool and quiet and call your vet if breathing becomes noisy or labored.

Questions

Frequently asked questions

How long is a Shih Tzu pregnant?

Shih Tzus are pregnant for about 63 days from ovulation, and most whelp in 62 to 63 days. Counted from a mating date, the normal range is 56 to 70 days, because conception can happen days after mating. Use the calculator on this page to get a date range.

How many puppies can a Shih Tzu have?

A typical Shih Tzu litter is about 4 puppies, with a range of 2 to 6. First litters and litters from older dogs are often smaller. An abdominal X-ray after day 50 gives the actual count.

Does a Shih Tzu need a C-section?

The risk of a C-section is moderate for Shih Tzus. An X-ray around day 50 helps your vet decide between natural whelping and planned surgery.

What are the signs a Shih Tzu is pregnant?

Around three to four weeks you may notice a smaller appetite, pinker and larger nipples and a clear mucus discharge. Her belly grows from about week six. Confirm with an ultrasound at about day 25 to 30.

When should a pregnant Shih Tzu have an X-ray?

Between about day 50 and day 55. By then the puppies’ skeletons show, so your vet can count them and compare head size with her pelvis.
