What causes a dog to have a miscarriage?

Answered by John Hunt

A dog can experience a miscarriage, also known as a spontaneous abortion, for various reasons. One of the most common causes is fetal death, which can occur due to a hormonal imbalance. Hormones play a crucial role in maintaining a healthy pregnancy, and any disruption in their balance can lead to complications.

There are several factors that can contribute to a hormonal imbalance in dogs, leading to fetal death and subsequent miscarriage. One such factor is inadequate progesterone levels. Progesterone is a hormone essential for maintaining pregnancy, as it helps support the growth and development of the fetus. If a dog’s progesterone levels drop too low, it can result in fetal death and subsequent miscarriage.

Another possible cause of hormonal imbalance is an overproduction of estrogen. Elevated estrogen levels can disrupt the delicate hormonal balance necessary for a successful pregnancy, potentially leading to fetal death and miscarriage. This can occur due to conditions such as ovarian cysts or certain hormonal disorders.

Infections and diseases can also contribute to miscarriages in dogs. Common examples include Brucellosis, a bacterial infection that can cause infertility and fetal death, and Canine Herpesvirus, which can lead to abortion in late pregnancy. These infections can affect the overall health and well-being of the mother and the developing fetuses, increasing the risk of miscarriage.

Other factors that can cause a dog to have a miscarriage include trauma or injury to the abdomen, exposure to certain toxins or medications, nutritional deficiencies, and genetic abnormalities in the fetus. It’s important to note that not all miscarriages are preventable, as some can occur due to factors beyond our control.

If you suspect that your dog may be experiencing a miscarriage, it’s crucial to seek veterinary attention immediately. The veterinarian will be able to assess the situation, determine the cause of the miscarriage, and provide appropriate treatment and care.

After a planned abortion, it is normal for a dog to experience some bleeding. This bleeding typically occurs within the first few days following the procedure and should gradually decrease over time. However, it’s important to closely monitor your dog and contact your veterinarian if the bleeding becomes excessive or persists for an extended period.

In addition to monitoring for bleeding, you should also watch out for other potential side effects or health issues following an abortion. These can include signs of infection, such as fever, lethargy, or loss of appetite, as well as any unusual or concerning behavior. It’s crucial to maintain open communication with your veterinarian and seek their guidance if you have any concerns about your dog’s post-abortion recovery.

A hormonal imbalance leading to fetal death is a common cause of spontaneous abortion in dogs. Other contributing factors can include infections, trauma, toxins, nutritional deficiencies, and genetic abnormalities. If you suspect a miscarriage, prompt veterinary attention is necessary. Following a planned abortion, monitoring for bleeding and any other potential side effects or health issues is crucial.
