When Labor Gets Stuck: What to Know About Dystocia in Pets

Understanding Labor and Dystocia in Dogs and Cats

A normal labor process in dogs and cats progresses in three main stages. It’s essential for pet owners to recognize the signs of normal labor and identify potential complications like dystocia, which is a difficult or obstructed birth. Here’s what to expect during each stage of the process.

Stage 1: Early Labor (Duration: Few hours to up to 24 hours)

In the initial phase of labor, your pet may exhibit various signs as her body prepares for delivery:

• Behavioral Changes:

  • Nesting (preparing a safe space)

  • Panting and trembling

• Appetite Changes:

  • Decreased appetite or refusal to eat

  • Occasional nausea and vomiting

• Vaginal Discharge:

  • Clear, watery discharge (if present)

These signs can appear intermittently and may last several hours.

Stage 2: Active Labor and Delivery (Duration: 3-12 hours, up to 24 hours)

This is the stage where active contractions occur and the actual delivery of the puppies or kittens begins.

• Visible Signs:

  • Noticeable contractions

  • The mother begins pushing to deliver her babies

• Time Between Deliveries:

  • Usually 1-2 hours between each delivery, but can vary

• Total Delivery Time:

  • Most deliveries occur within 30-60 minutes between puppies/kittens, but it can last up to 24 hours

• Vaginal Discharge:

  • Can range from clear to greenish (due to uteroverdin) or slightly bloody

• Behavioral Changes:

  • Loss of appetite

  • Panting and trembling
    

During this stage, it is critical to monitor for any signs of complications, such as prolonged labor or abnormal discharge, which may indicate a need for medical intervention.

Stage 3: Afterbirth (Delivery of the Placenta)

After each puppy or kitten is delivered, the placenta will follow. This is the final stage of labor.

• Placenta Delivery:

  • Each fetus is followed by its placenta, although they may not be expelled at the exact same time.

• Transition Between Stages:

  • In many cases, stages 2 and 3 overlap as the mother delivers both her babies and the placentas.
    

Important Note: While a normal delivery involves the passage of both the fetuses and placentas, if the placenta is retained or if the mother experiences prolonged or difficult labor, immediate veterinary care is required to prevent complications.

So what is dystocia and how to recognize signs leading to it?

Dystocia refers to a difficult birth or the inability to deliver a fetus through the birth canal without medical intervention. This condition can be distressing and requires prompt veterinary care to ensure the safety of both the mother and her offspring.

Causes of Dystocia

Dystocia can arise from a variety of factors, which may be due to issues with the mother, the fetus, or both. The primary causes include:

• Maternal Factors:

  • Uterine inertia (weak or absent contractions)

  • Pelvic abnormalities or other anatomical issues

  • Certain breeds may be more predisposed to complications during labor

• Fetal Factors:

  • Oversized fetuses that are too large to pass through the birth canal

  • Mispositioned fetuses (such as a breech presentation)

• Combination of Maternal and Fetal Factors:

  • Some cases involve both maternal and fetal complications contributing to the difficult labor.
    

The most common cause of dystocia is secondary uterine inertia, which occurs when the uterus stops contracting properly after the delivery of one or more puppies or kittens, leading to a delay in the birth of the remaining offspring.

Signs of Dystocia: When to Seek Emergency Care

Dystocia, or difficult labor, requires prompt veterinary attention to ensure the safety of both the mother and her newborns. Below are key signs to watch for that may indicate your pet is experiencing dystocia and needs immediate assistance. Signs to Watch For:

• No Progress After Strong Contractions:

  • If the mother is having strong contractions for over 2 hours without delivering any puppies or kittens, this could signal dystocia.

• Excessive Time Between Deliveries:

  • A gap of more than 2 hours between the birth of puppies or kittens may suggest a delay in the labor process, which could be caused by dystocia.

• Weak or Infrequent Contractions:

  • When contractions are weak, infrequent, or fail to progress, it can indicate uterine inertia, a common cause of dystocia. This condition leads to insufficient uterine contractions, preventing the delivery of the offspring.

• Signs of Fetal Distress:

  • If the mother is showing signs of excessive discomfort or if the puppies or kittens appear stressed—such as a lack of movement or abnormal heart rates (detectable via ultrasound)—this can indicate that the fetuses are in distress and require urgent medical attention.

Treatment for Dystocia: What to Expect

When dystocia is diagnosed, the treatment plan will depend on the underlying cause and severity of the condition. Your veterinarian will assess the situation and choose the most appropriate course of action to ensure the safety of both the mother and her babies.

Treatment Options for Dystocia:

• Medications:

  • Oxytocin: This medication may be used to stimulate uterine contractions. It is carefully monitored to assess the mother's response and ensure that contractions are progressing normally.
    

• Surgical Intervention:

  • Caesarean Section (C-Section): If the uterus is unresponsive to medication (uterine inertia), there is an obstruction during delivery, or the fetuses are in distress despite medical management, a C-section may be necessary. This surgery is commonly performed when there is a significant risk to the mother or puppies/kittens.

Conclusion: The Importance of Timely Care

Dystocia presents risks for both the mother and her offspring. Early recognition, accurate diagnosis, and prompt treatment are essential to ensuring the best possible outcome. If you suspect that your pet is experiencing difficulty during labor, don’t hesitate to contact us or your preferred veterinary team for evaluation and care. Quick intervention can make all the difference in a safe delivery.
