What Does It Mean When a Pregnant Dog Breathes Heavy? (10 Reasons Why)


Dogs are social and active animals that are kept as pets by humans. Their lovable and docile nature contributes greatly to their mutual relationship with humans. Dogs experience several physiological phenomena that can leave you worried.

You might have noticed your expectant dog breathing heavily, and you might be worried about what it could mean. The following are ten reasons why this may be so:

1. Anxiety Due to Warmth

Dogs may breathe heavily during pregnancy to cool themselves down, especially in hot weather or when they lack proper ventilation. Ensure your dog gets enough ventilation when expecting to reduce heat stress. 

2. Weight Gain

As the pregnancy progresses, the dog’s abdomen enlarges, putting pressure on the diaphragm. This can lead to heavier breathing. You can walk with your expectant dog or play with it to get it to exercise and lose some weight. 

3. Fluctuation of Hormones 

When dogs are pregnant, their hormones tend to change to facilitate the growth of the puppies. Pregnancy hormones can affect the respiratory system, causing a pregnant dog to breathe heavily.

4. Oxygen Supply

As the puppies develop and grow, the mother’s body requires more oxygen, leading to increased respiration. This could cause your dog to breathe heavily. 

However, if the breathing continues without reducing, then you should contact your vet, as it can be a respiratory disorder. 

5. Physical Pressure

Pregnancy can be physically demanding for a dog, and heavy breathing may occur after exercise or strenuous activity. Even though physical fitness is good for your pregnant dog, it should be moderate. 

6. Nervousness

Generally, dogs are active and playful animals. Pregnant dogs may become more easily excited, especially when they miss you, or anxious when taken to the vet, which can result in heavy breathing. 

7. Respiratory Illness 

Heavy breathing can indicate an underlying respiratory infection or illness. It is important to monitor for other symptoms and consult a veterinarian if any concerns arise.

8. Cardiovascular Disorder

Pregnant dogs with heart conditions may experience heavy breathing due to decreased cardiac function or fluid accumulation. 

You should regularly visit the vet to ensure your pregnant dog is safe. 

9. Insufficient Blood

If a pregnant dog becomes anemic and has a low red blood cell count, it can cause heavy breathing as the body tries to compensate for decreased oxygen-carrying capacity.

10. Intricacies

Heavy breathing can be a sign of complications during pregnancy, such as milk fever, uterine infection, or preterm labor. 

If there are concerns about the dog’s health or if heavy breathing is accompanied by other unusual symptoms, it is important to consult a veterinarian immediately. 

Is It Normal For Pregnant Dogs to Breathe Heavily? 

Yes, it is normal for pregnant dogs to breathe heavily during certain stages of their pregnancy. As a dog’s pregnancy progresses, the growing fetus puts pressure on the diaphragm and lungs, which can cause the dog to breathe more heavily.

Additionally, hormonal changes and increased blood flow during pregnancy can also contribute to heavier breathing.

Do Dogs Breathe Heavily Before Labor?

Yes, dogs can breathe heavily before going into labor. This heavy breathing, also known as panting, is a normal physiological response during labor.

Panting helps dogs regulate their body temperature and cope with the physical exertion of labor. 

However, if you notice excessive or labored breathing, it is important to consult a veterinarian to assess the dog’s condition and determine if there are any underlying health issues causing the heavy breathing.  

What Stage of Labor Is a Dog Panting? 

During the first stage of labor in dogs, also known as the preparatory stage, dogs display signs such as panting, restlessness, nesting behavior, and a decrease in appetite. 

This stage occurs before active labor and is characterized by the cervix starting to dilate and the onset of contractions. 

Pregnant Dog Panting How Long Till Birth?

Similarly, you might ask, How long after my dog starts panting will she give birth? 

Every dog is different, and the duration between panting and giving birth can vary. Panting in dogs can be a sign that labor is approaching, as they often pant during the active stage of labor.

Furthermore, dogs begin to pant heavily and show signs of restlessness a few hours before giving birth. 

This panting is caused by increased abdominal pressure and contractions as their body prepares for delivery.

However, it’s crucial to know that the duration of panting can vary significantly among individuals.

Why Is My Dog Panting and Shaking After Giving Birth?

The following are five reasons that explain why your dog is panting and shaking after giving birth:

1. Regulating Body Temperature

Panting is a normal response for dogs to regulate their body temperature, especially after giving birth. The process of labor and birth can increase their body temperature, and panting helps them cool down.

2. Postpartum Hormonal Changes

After giving birth, dogs experience significant hormonal changes. These hormonal shifts can induce nesting behavior, as they are instinctively preparing a safe and comfortable space for their puppies.

Panting can be a result of these hormonal changes as well.

3. Physical Exertion

Giving birth is a physically demanding process for dogs. The labor and delivery process can be exhausting, which may cause panting.

Additionally, nesting involves a lot of physical activity, such as digging and arranging bedding materials, which can further contribute to panting.

4. Apprehension

Dogs can experience anxiety and stress after giving birth. The responsibility of caring for newborn puppies, coupled with changes in their environment, can be overwhelming.

Panting can be a sign of stress or anxiety in dogs, and nesting behavior may also indicate a desire for security and comfort.

5. Physical Discomfort

Dogs may experience physical discomfort after giving birth. The process of delivering puppies can cause soreness, cramps, and even minor injuries. 

Panting can be a way for dogs to cope with pain or discomfort, as well as a response to the physical exertion involved in giving birth.

Pregnant Dog Panting and Shaking

It’s normal for pregnant dogs to pant more as they near their due date as their bodies undergo hormonal and physiological changes. However, excessive panting and shaking could indicate potential problems, and it’s important to consult a veterinarian for a proper evaluation.

Furthermore, there are several issues that could potentially cause these symptoms in a pregnant dog. One possibility is that the dog is experiencing pain, which could be a sign of complications during pregnancy. Another possibility is anxiety, as dogs can become anxious or fearful during pregnancy.
