Retention of Fetal Membranes (Retained Placenta) in Dogs

Occurrence: common
Location of illness: Abdomen/pelvis

Retention of fetal membranes, also known as retained placenta, is a condition in dogs where the placenta or parts of it are not expelled after the birth of a puppy. This can lead to serious health complications if not treated in a timely manner.

The most important facts at a glance

Retention of fetal membranes, also known as retained placenta, is a condition in which the placenta is not completely expelled after birth. In dogs, the placenta should normally be expelled within 15 minutes after the birth of each puppy. Causes can include inadequate uterine contractions, hormonal imbalances, or structural abnormalities of the uterus. Symptoms include greenish-black vaginal discharge, Fever, and loss of appetite. Diagnosis is made by clinical examinations, ultrasound, and blood tests to detect infections or Inflammatory conditions. Treatment varies depending on the severity; mild cases can be treated with oxytocin, while more severe cases may require antibiotics or even surgery. The prognosis is good with early diagnosis and treatment, but untreated cases can lead to serious complications. For prevention, dogs should be closely monitored during pregnancy and birth. Research focuses on hormonal changes, genetic predispositions, and alternative therapeutic approaches. The role of nutrition is also being investigated to minimize the risk. The development of new diagnostic tools could improve the early detection and treatment of retention of fetal membranes, leading to better outcomes and a higher quality of life for affected dogs.

Causes

The birthing phase in dogs is typically divided into three stages: the preparatory phase, the expulsion phase, and the afterbirth phase. During the afterbirth phase, the placenta, which provided the puppy with nutrients during pregnancy, is expelled. This usually occurs within 15 minutes after the birth of each puppy. Retention of the placenta can occur if the dog’s body cannot effectively expel the placenta.

One of the main causes of retention of fetal membranes in dogs is inadequate contraction of the uterus, which can prevent the placenta from being completely expelled. These inadequate contractions can be caused by various factors, including hormonal imbalances or a general weakness of the uterine muscles.

Other causes may include structural abnormalities of the uterus, infections, or Inflammatory conditions. Incomplete separation of the placenta from the uterine wall can also play a role. Sometimes, the placenta can also be retained due to mechanical blockages, such as a large litter that overstretches the uterus.

Common symptoms:

Rare symptoms:

The symptoms of retained placenta in dogs can vary but are often quite clear. A common sign is the appearance of greenish or foul-smelling discharge from the dog’s vagina a few hours to days after giving birth. This may indicate an infection caused by the retained placenta.

Another symptom may be Fever, which is often associated with a bacterial infection. The dog may also show signs of Pain or discomfort, including restlessness, trembling, or even loss of appetite. In some cases, abdominal swelling may occur if fluid or pus accumulates in the uterus.

Another serious symptom that can occur is general lethargy or weakness, which indicates that the dog may be suffering from a systemic infection. In severe cases, septic shock can occur, which can be life-threatening.

Diagnosis

The diagnosis of retention of fetal membranes usually begins with a thorough clinical examination of the dog. The veterinarian will take a detailed history, including the number of puppies born, the duration of labor, and any observed abnormalities. A physical examination will be performed to identify signs of Fever, Pain, or abnormal discharge.

Imaging procedures such as ultrasound can be used to determine if placental remnants are present in the uterus. An ultrasound can help examine the uterus for remaining placental tissue or fluid accumulation.

In addition, blood tests can be performed to detect signs of infection or inflammation. A complete blood count may show elevated white blood cells, indicating an infection. In some cases, a bacterial culture of the vaginal discharge may be performed to identify the exact type of infection.

Therapy

Treatment for retention of fetal membranes depends on the severity of the condition. In mild cases, medication with oxytocin, a hormone that stimulates uterine contractions, may be sufficient to expel the placenta. Oxytocin is usually administered by injection and can help stimulate the uterus to expel any remaining placental tissue.

In more severe cases, especially if there is an infection, it may be necessary to administer antibiotics to combat the infection. The choice of antibiotic depends on the type of infection, which can be identified by a bacterial culture. Pain relievers can also be prescribed to relieve the dog’s discomfort.

In extreme cases, or if other treatments are not successful, surgery may be necessary to remove the remaining placenta. This procedure is usually considered a last resort, as it carries additional risks.

Prognosis and follow-up care

The prognosis for dogs with retention of fetal membranes depends on the speed of diagnosis and the effectiveness of treatment. With early detection and appropriate treatment, the prognosis is usually good. Most dogs recover completely if the placenta is removed in time and an infection is treated effectively.

However, if the condition is not treated in a timely manner, it can lead to serious complications, including severe infections, uterine inflammation (metritis), or even sepsis, which can be life-threatening. In such cases, the prognosis may be considerably less favorable.

In the long term, fertility problems can also occur, especially if the uterus has been damaged by an infection or surgery. It is important to carefully monitor the dog during the recovery phase and ensure that she receives the full support she needs.

Prevention

To minimize the risk of retention of fetal membranes, dogs should be closely monitored during pregnancy and birth. Appropriate prenatal care can help identify and treat potential problems early on. It is important that the birth takes place in a clean and stress-free environment to minimize the risk of infection.

After the birth, the dog and her puppies should be examined regularly by a veterinarian to ensure that all placentas have been expelled and that there are no signs of infection. The veterinarian can also provide recommendations on the dog’s nutrition and care to support her recovery.

In dogs who have had problems with retained placenta in the past, prophylactic treatment with oxytocin may be considered to facilitate the expulsion of the placenta. However, this should only be done under the guidance of a veterinarian.

Outlook on current research

Retention of fetal membranes, also known as retained placenta, is a condition in which the placenta or parts of it are not completely expelled after birth. While this condition has been more frequently studied in other animal species, such as cattle and horses, there are fewer comprehensive studies in dogs. Nevertheless, scientific interest in retained placenta in dogs has increased in recent years, as reproduction and birth in dogs are increasingly becoming the subject of veterinary medical research.

Current research projects focus on the hormonal changes that occur during and immediately after birth to better understand how these processes affect placental expulsion. In particular, the role of oxytocin, a hormone responsible for uterine contraction, is being intensively studied in research. Researchers are trying to find out whether an insufficient production or effect of oxytocin could contribute to retained placenta in dogs. Initial results suggest that administering oxytocin in certain dosages could help to completely expel the placenta.

Another important aspect of the research is the investigation of genetic predispositions. Some dog breeds appear to be more susceptible to retention of fetal membranes, suggesting that genetic factors may play a role. Studies that identify genetic markers could help breeders and veterinarians in the future to provide warnings and take preventive measures to reduce the risk of this condition.

In terms of treatment options, researchers are also interested in developing alternative therapeutic approaches that are less invasive than current practice. These include, for example, herbal or homeopathic preparations that could support the contractile function of the uterus without causing the side effects of synthetic drugs.

The role of nutrition is also being investigated in current research. Some studies suggest that certain nutrient deficiencies during pregnancy could increase the likelihood of retained placenta. Researchers are working to develop specific nutritional plans that reduce the risk of such complications.

Another promising area of research is the development of diagnostic tools that enable the early detection of retention of fetal membranes. Currently, most diagnoses are clinical, based on the dog’s symptoms and behavior after birth. The development of imaging devices or biochemical tests could enable a more accurate and faster diagnosis, which would lead to more effective treatment.

In summary, current research on retention of fetal membranes in dogs shows a growing interest in identifying the underlying causes and developing new treatment methods. While many questions remain open, the findings to date are promising and could lead to better treatment outcomes and a higher quality of life for affected dogs in the future.
