How long does a dog stay in false pregnancy?

Table of Contents

The average false pregnancy, or pseudopregnancy, in dogs typically lasts between 1 to 3 weeks after the expected end of a normal pregnancy period (around 63 days after ovulation). However, some dogs may show signs for a shorter or longer duration, depending on individual hormonal fluctuations and the severity of their symptoms.

Understanding Canine False Pregnancy: A Comprehensive Guide

False pregnancy, also known as pseudopregnancy or phantom pregnancy, is a relatively common condition in unspayed female dogs. It occurs due to hormonal changes that mimic the effects of actual pregnancy, even when the dog is not pregnant. While it can be distressing for both the dog and the owner, understanding the underlying mechanisms and symptoms is crucial for proper management and care. This article provides a detailed overview of canine false pregnancy, including its causes, symptoms, duration, and management strategies.

What Causes False Pregnancy?

False pregnancy is primarily caused by normal hormonal fluctuations during the estrous cycle (heat cycle) in unspayed female dogs. After ovulation, whether or not fertilization occurs, the ovaries produce progesterone. If the dog does not become pregnant, progesterone levels eventually decline, and prolactin levels increase. This rise in prolactin is what triggers the physical and behavioral signs of false pregnancy.

Progesterone: Initially high, this hormone prepares the uterus for implantation.
Prolactin: Rises after progesterone declines, mimicking pregnancy hormones.

The exact reasons why some dogs develop more pronounced false pregnancies than others are not entirely understood. However, it’s thought to be related to individual differences in hormone sensitivity and metabolism.

Symptoms of False Pregnancy

The symptoms of false pregnancy can vary in intensity from mild to severe. Some dogs may only exhibit subtle behavioral changes, while others may display a wide range of physical and psychological signs. Common symptoms include:

Nest-building: Creating a “nest” or den area.
Mothering behavior: Acting protective towards inanimate objects (toys, blankets).
Decreased appetite: Sometimes, but appetite can also increase.
Weight gain: Due to water retention.
Enlarged mammary glands: Often with milk production.
Lethargy: Reduced activity levels.
Abdominal distension: Swollen abdomen.
Vomiting: Rare, but possible.
Aggression: Especially around the “nest” or perceived “puppies.”

The severity and combination of these symptoms vary greatly between individual dogs. It is important to consult a veterinarian if you suspect your dog is experiencing a false pregnancy to rule out other underlying medical conditions.

Diagnosing False Pregnancy

Diagnosing false pregnancy typically involves a combination of:

Physical examination: The veterinarian will assess the dog’s physical condition, including the mammary glands and abdomen.
History: Gathering information about the dog’s recent heat cycles and behavior.
Ruling out actual pregnancy: Pregnancy can be confirmed through palpation (after 21 days), ultrasound (after 25 days), or radiography (after 45 days).
Blood tests: While not always necessary, blood tests can rule out other medical issues.

It is crucial to rule out actual pregnancy because the management strategies for false pregnancy and actual pregnancy are completely different.

Treatment and Management of False Pregnancy

In many cases, false pregnancy resolves on its own without any specific treatment. However, if the symptoms are severe or causing significant distress to the dog, veterinary intervention may be necessary.

Here are some common management strategies:

Ignore the behavior: Avoid reinforcing nesting or mothering behaviors.
Remove the “puppies”: Take away any objects the dog is nurturing.
Reduce food intake: Can help decrease milk production.
Increase exercise: Distracts the dog and reduces anxiety.
Elizabethan collar: Prevents the dog from licking or stimulating the mammary glands.
Medication: In severe cases, the veterinarian may prescribe medication to reduce prolactin levels.
Spaying: Spaying is the only permanent solution to prevent future false pregnancies.

Treatment Option	Description	Benefits	Risks
————————	—————————————————————————-	—————————————————————	————————————————————————-
Ignoring Behavior	Avoiding reinforcement of nesting and mothering instincts.	Simple, non-invasive, often effective for mild cases.	May not be sufficient for severe cases.
Removing “Puppies”	Taking away any objects the dog is nurturing.	Disrupts the false maternal bond, reduces distress.	May cause temporary anxiety.
Reducing Food Intake	Limiting the dog’s calorie intake.	Helps decrease milk production.	May lead to nutritional deficiencies if not carefully monitored.
Increasing Exercise	Engaging the dog in more physical activity.	Distracts the dog, reduces anxiety, promotes overall health.	May not be suitable for dogs with underlying health conditions.
Elizabethan Collar	Prevents the dog from licking or stimulating the mammary glands.	Reduces milk production, prevents mastitis.	Can be uncomfortable for the dog.
Medication	Drugs to reduce prolactin levels (e.g., cabergoline).	Effective in suppressing symptoms.	Potential side effects, requires veterinary prescription and monitoring.
Spaying	Surgical removal of the ovaries and uterus.	Permanent solution, prevents future false pregnancies.	Surgical risks, requires anesthesia.

Spaying: The Definitive Solution

Spaying (ovariohysterectomy) is the most effective long-term solution for preventing false pregnancy. By removing the ovaries, the source of the hormones that trigger false pregnancy is eliminated. Spaying also offers other health benefits, such as preventing uterine infections (pyometra) and reducing the risk of mammary cancer.

Potential Complications

While false pregnancy is usually a self-limiting condition, potential complications can arise:

Mastitis: Inflammation of the mammary glands.
Self-trauma: Excessive licking or chewing of the mammary glands.
Depression: Prolonged or severe depression.
Aggression: Increased aggression, especially towards other animals or people.

If you observe any of these complications, it’s essential to seek veterinary attention promptly.

Frequently Asked Questions (FAQs)

How long does a dog stay in false pregnancy?

As mentioned above, the average false pregnancy lasts between 1 to 3 weeks. However, the duration can vary depending on the individual dog and the severity of their symptoms. Some dogs may only show signs for a few days, while others may exhibit symptoms for several weeks.

Is false pregnancy common in dogs?

Yes, false pregnancy is relatively common in unspayed female dogs. Some studies suggest that up to 75% of unspayed female dogs may experience some degree of false pregnancy after their heat cycle.

Can a dog have a false pregnancy without producing milk?

Yes, a dog can experience a false pregnancy without producing milk. The presence and amount of milk production can vary widely among individual dogs. Some dogs may have enlarged mammary glands without any noticeable milk production, while others may produce a significant amount of milk.

What is the best way to stop milk production during a false pregnancy?

There is no single “best” way, but several strategies can help reduce milk production: Reduce food intake slightly (but avoid starvation), increase exercise to distract the dog, and prevent the dog from licking her mammary glands using an Elizabethan collar. In severe cases, the veterinarian may prescribe medication to reduce prolactin levels. Never express the milk manually, as this can stimulate further production.

Is false pregnancy painful for dogs?

False pregnancy is generally not physically painful, but it can be uncomfortable due to enlarged mammary glands and abdominal distension. The behavioral changes associated with false pregnancy, such as nesting and anxiety, can also be distressing for the dog.

Can spaying a dog during a false pregnancy cause problems?

Spaying a dog during a false pregnancy is generally safe, but it is best to discuss this with your veterinarian. The veterinarian may recommend waiting until the symptoms of false pregnancy have subsided before performing the surgery, as the mammary glands can be engorged and more prone to bleeding.

How can I tell the difference between a false pregnancy and a real pregnancy?

The only way to definitively determine if a dog is pregnant is through veterinary examination. Palpation can be performed after 21 days, ultrasound after 25 days, and radiography after 45 days. Early pregnancy and false pregnancy can have similar symptoms, so professional diagnosis is crucial.

Are certain breeds more prone to false pregnancy?

There is no definitive evidence to suggest that certain breeds are more prone to false pregnancy than others. However, anecdotal evidence suggests that some breeds may be more likely to exhibit pronounced symptoms.

Can a dog still get pregnant after having a false pregnancy?

Yes, a dog can still get pregnant after having a false pregnancy. False pregnancy does not affect fertility.

How often can a dog experience false pregnancy?

A dog can experience false pregnancy after each heat cycle if she is not spayed. The frequency and severity of false pregnancies can vary throughout a dog’s life.

Is it cruel to take away the “puppies” from a dog experiencing a false pregnancy?

While it may seem cruel, removing the “puppies” (toys, blankets) is actually beneficial in the long run. It helps break the false maternal bond and reduces the dog’s distress.

What happens if a dog is left untreated during a false pregnancy?

In most cases, false pregnancy resolves on its own without treatment. However, if the symptoms are severe, persistent, or leading to complications like mastitis or self-trauma, treatment is necessary to alleviate the dog’s discomfort and prevent further health problems. Prolonged and untreated false pregnancies can also cause the dog unnecessary stress.
