Understanding the Common Causes of Puppies Being Born Prematurely

Typically, a bitch's gestation period lasts around 63 days. Puppies born before this time, often within the first 58 days, are considered premature. These little ones are significantly smaller and less robust than their fullterm counterparts, which often results in lower survival rates. Several factors can lead to premature births in dogs:

1. Genetic Factors

Genetic anomalies in bitches can trigger premature uterine contractions, leading to early labor. Some dog breeds are more prone to premature births and miscarriages than others.

2. Bacterial Infections

Bacterial infections are a leading cause of premature labor in bitches. Many bitches experience early labor due to infections during pregnancy. For instance, Lyme disease can trigger premature labor and, in severe cases, complications affecting the kidneys, nervous system, and heart, posing a significant threat to the bitch's life. Brucellosis is another common bacterial infection linked to spontaneous abortions in bitches.

3. Viral Infections

Maternal infection with parvovirus or canine herpesvirus can lead to premature labor or miscarriage. Parvovirus, particularly virulent, can manifest in vomiting and diarrhea and may also infect the myocardium, causing heart issues and threatening the dog's life.

4. Ovarian Cysts

Unspayed bitches, especially older ones, may develop ovarian cysts. These, along with other tumors, can also cause premature labor. If a tumor is detected in a bitch, immediate treatment is essential.

5. Injuries

Any injury, particularly to the uterus, can lead to premature labor. Accidents, such as falls or collisions, can harm the fetus and even result in the death of the bitch and her puppies. Stillbirths can also trigger premature labor in other puppies.

6. Excessive Stress

Pregnant dogs can be affected by stress, which can negatively impact their puppies. Chronic stress can significantly harm the developing fetus.

7. Weak Constitution

Dogs with a weak constitution are not ideal candidates for pregnancy, as they are more prone to premature labor. If a dog with a weak constitution becomes pregnant, it's crucial to consult a veterinarian for advice on whether to induce labor or continue the pregnancy. If the pregnancy is allowed to continue, adequate nutrition is vital.

8. Parasitic Infections or Incorrect Medication

Toxoplasmosis is a leading cause of spontaneous abortions, premature labor, and malformed puppies. Therefore, it's essential for pet owners to ensure their dogs are dewormed before breeding. If a dog falls ill during pregnancy, immediate veterinary care is necessary, and strict adherence to the vet's medication instructions is crucial to avoid complications.

9. Overexertion

Pregnant dogs should avoid strenuous exercise, as it can contribute to premature labor. While daily walks are fine, activities like running, chasing, or fighting should be avoided. Additionally, dogs can experience premature labor if they are startled or stressed during pregnancy, so it's important to minimize such situations.

These are the common causes of premature labor in puppies. As pet owners, it's crucial to take preventive measures to ensure the health and safety of pregnant dogs, helping them deliver their puppies safely and welcoming new life joyfully.
