Definition
A prolonged gestation in dogs over 72 days refers to a pregnancy length that lasts longer than the normal gestation period of around 63 days. This can indicate various health problems and usually requires a veterinary examination.
Can Occur with the Following Diseases:
Basics and possible causes
The normal gestation length in dogs averages 63 days, although slight variations can occur depending on the breed and individual factors. A pregnancy that goes beyond 72 days is considered prolonged and could indicate complications that may endanger the wellbeing of the mother or the puppies.
One possible cause of a prolonged pregnancy is a miscalculation of the mating date. Often, the first mating is assumed to be the start of pregnancy, even though fertilization may not occur until a few days later. This can lead to an apparent prolongation of the pregnancy.
Another cause may be a hormonal dysfunction that disrupts the normal course of labor. Progesterone, which supports the uterus during pregnancy, must drop toward the end of gestation to initiate birth. A persistently high progesterone level can delay the onset of labor.
There are also pathological causes of prolonged pregnancy, such as fetal abnormalities or uterine atony, a condition in which the uterus is unable to contract sufficiently to trigger birth.
Typical accompanying symptoms
-
No signs of labor: If the bitch still shows no signs of labor after more than 70 days, this may indicate a prolonged pregnancy. Typically, labor begins with restlessness, nesting behavior, and contractions.
-
Loss of appetite: Prolonged gestation can be associated with decreased food intake, as the pressure on the stomach increases due to the fetuses.
-
Lethargy: The bitch may seem tired or less active, which can indicate stress or discomfort.
-
Discharge: Abnormal vaginal discharge, especially if it smells foul or is discolored, can indicate an infection or other problems.
-
Abdominal pain: If the dog is sensitive to touch on the abdomen or licks itself frequently, this could indicate Pain or discomfort.
When to visit the vet?
A veterinarian should definitely be consulted if the pregnancy goes beyond 72 days to check the health of the bitch and the puppies. Delays can increase the risk of complications.
If the bitch shows signs of discomfort, such as heavy discharge, abdominal pain, or lethargy, immediate veterinary intervention is necessary. These symptoms could indicate serious complications such as a uterine infection or fetal stress.
An immediate visit to the veterinarian is also advisable if the bitch shows signs of labor but it does not progress or no puppies are born. This could indicate birth complications that require medical intervention.
Symptom recognition for animal owners and veterinary diagnostic procedures
For pet owners, it is important to recognize the signs of a prolonged pregnancy. This includes monitoring the bitch’s behavior and physical changes. Knowing the mating date precisely can also help determine whether the pregnancy is prolonged.
The veterinarian will usually perform a thorough examination to determine the cause of the prolonged pregnancy. This often includes an ultrasound to check the health and position of the fetuses. X-rays may also be taken to determine the number of fetuses and to see whether there are any abnormalities.
Blood tests may be performed to check the bitch’s hormonal status, especially the progesterone level, which plays an important role in the onset of labor. An abnormal hormone level can indicate a hormonal dysfunction.
What can pet owners do and professional therapy options
The pet owner should pay close attention to the health and behavior of their bitch and consult a veterinarian promptly if there are signs of discomfort or a prolonged pregnancy. Early intervention can often prevent serious complications.
At home, the pet owner can ensure the bitch has a calm, low-stress environment to make whelping easier. Adequate fluid intake and a balanced diet are also important to support the bitch’s health.
It is important not to stress or overexert the bitch unnecessarily. Instead, allow her plenty of rest and make sure she feels safe and secure. Regular but gentle exercise can also be helpful in supporting the whelping process.
Outlook on current research
Prolonged pregnancy in dogs beyond 72 days is a symptom receiving increasing attention in veterinary research. Current studies are investigating the genetic and hormonal factors that can lead to prolonged pregnancy. In particular, researchers are examining how the interaction between progesterone and other hormones affects the normal course of pregnancy. Researchers are trying to determine whether genetic predispositions play a role in prolonged gestation by studying different dog breeds and their specific genetic markers.
There are also studies on the role of environmental factors and stress that may influence the length of pregnancy. This includes analyzing nutrition, housing/keeping conditions, and the pregnant bitch’s overall wellbeing. Through controlled studies, researchers aim to find out how these factors affect hormonal processes during pregnancy. There are indications that a low-stress environment and optimal nutrition could have positive effects on the regularity of pregnancy.
Experimental research is also developing new diagnostic techniques to counteract prolonged pregnancy at an early stage. Ultrasound examinations and blood tests to monitor hormonal changes are being further refined to enable more accurate predictions of the whelping date. Another area of research is the development of new therapeutic approaches that intervene at the hormonal level to regulate the length of pregnancy without endangering the health of the bitch or the puppies.
Research is also looking at how prolonged pregnancy affects the puppies’ development in the womb. Initial findings suggest that an excessively long pregnancy may increase the risk of birth complications and developmental disorders in puppies. Long-term studies in different dog populations are intended to help better understand the potential risks and develop prevention strategies.
