How to tell your ShihTzu is pregnant?

How to tell your ShihTzu is pregnant?

Let us learn various different ways to know if your Shih Tzu is pregnant or not.


1. Psychological changes

Behavior change is a major part of pregnancy. If your dog is pregnant, you can detect her behavior. 

Either she will look for extra love, care, attention, or seek isolation and no disturbance. 

Isolation is not healthy because it determines that she is in depression.


2. Changes in appetite

As per the stage of pregnancy, the diet of Shih Tzu will also oscillate. You will notice she will throw up food sometimes or eat less food.

On the other hand, you may also notice her eating a lot and still be unhappy with her meal. It is primarily because of changes in hormones.


3. Size of the nipples changes

During the early stage of pregnancy, Shih Tzu’s nipples get enlarged. The areolas will take rounded shapes, which were usually flat before pregnancy.

You will see the color of the nipple will become slightly dark and red. This indicates an increase in blood flow.

Later the nipples will be able to carry milk for lactation.


4. Feeling lethargic

If you notice your Shih Tzu is feeling tired all day and spends the majority of the day taking a nap, then it is also a signal of pregnancy.

If she is ordinarily enthusiastic, this decrease in energy should be carefully considered. 

We know it may be challenging to identify a decrease in energy in dogs who are accustomed to sleeping for long periods of time.

But try to pay closer attention to how quickly she tires during walks during such cases.


5. Vulva

The next sign for a pregnant Shih Tzu is to look for the swollen vulva.

However, unlike swelling caused by heat, the vulva does not bleed in this circumstance, and the swelling will not subside until the baby is born.

Keep an eye on her if she excessively licks her vulva, which means it is creating irritation, and she is soon going to give you more baby Shih Tzu.


6. Pregnancy Bump

This is a clear symptom of pregnancy, specifically if there is no single reason for sudden weight gain. 

During pregnancy, the dog’s abdomen tends to enlarge.

Generally, you will see her baby belly in the starting phase of the third week. 

Yes, the speed is pretty slow. This means that by the time you will know she is pregnant, it will be time to take her to the vet for delivery.


7. Nesting Behaviors

Are you wondering what nesting behavior is? 

When a female dog gets pregnant, she starts preparing her surroundings for the arrival of new puppies.

When your Shih Tzu is pregnant, she will also start preparing for the birth of her puppies.

For that, she will tear newspapers, rip blankets, and gather toys in a specified location to make a nest and to satisfy her mothering urge.

She may become cranky and reclusive during this period, so it’s better to restrict her contact with your children.


8. Hormone tests

You can also take the hormonal test to confirm your Shih Tzu is pregnant other than symptoms.

If Shih Tzu is going to conceive, then she is likely to release the Relaxin hormone. It is produced only in the placental tissue at the time of pregnancy. 

Thus, when you take your dog to the vet, he will conduct the test to look for relaxin hormone.

Note: For the test to be accurate, the mother must be at least 30 days pregnant. Relaxin levels rise throughout pregnancy and drop quickly after delivery.


9. Palpation

The membranes that surround each fetus grow to produce fluid-filled sacs as the dog fetus starts developing.

Generally, between the 21st and 35th day of pregnancy, these sacs are palpable.

It will expand and develop into a size of tennis ball nearby around 45 pounds.

Note: The sacs lose their unique structure after a month, and the uterus has a floppy feel that could be mistaken for fat or a pyometra.

You can opt for palpation. It is the most cost-effective and practical method of determining whether or not a dog is pregnant.


10. X-ray

The use of X-rays to diagnose pregnancy in Shih Tzu is 100 percent accurate, but the one drawback is that it cannot be used early.

However, in the later pregnancy stage (nearly 55 days) X-ray can help you to know:

How many babies are present inside her tummy and to figure out when the optimal time is to have an elective cesarean.


11. Ultrasound

Ultrasonography can be used to confirm pregnancy in humans. Similarly, puppies can be scanned using ultrasonography.

It is a very helpful method to determine Shih Tzu’s gestation at an early stage. 

It can be conducted between 25-35 days of pregnancy. During the ultrasound, you cannot just confirm the presence of the baby but also know their heartbeats.

It can also assist in determining the gestational age of the fetus and filter out many other causes of uterine distension, such as pyometra.

After confirming that your Shih Tzu is pregnant, learn every stage of her pregnancy in the upcoming section.

Let’s understand the week-by-week pregnancy stage of mommy Shih Tzu.


Pregnancy Stage of a Shih Tzu

Pregnancy Stage of a Shih Tzu

First and the second week.

In the first week, your Shih Tzu will be inseminated. The fertilization starts taking place in the uterine tube.

The ovum (a single cell that has been discharged from one of the female reproductive organs) starts to divide and goes down into the uterus.

The ovum floats freely in the uterus, and the placenta develops from the ovum’s yolk sac.

At this stage, Shih Tzu will feel a bit sluggish and may face motion sickness.

You may see pink discharge coming from her body. Don’t panic. It is not a sign of miscarriage.

You no need to make any change in her diet or routine.


Third week

In this week, the fetus will grow and start taking shape. It will be very tiny in size, nearly around 1 inch long.

The embryo starts sticking to the uterine wall. The central nervous system begins to form. 

Yet there is no need to change mommy Shih Tzu’s diet or exercise at this stage. However, she will become more hungry and wish to put in more calories.


Fourth week

It is the crucial stage of pregnancy because there are higher chances of miscarriage. Things will eventually start taking shape.
