If a female dog's pregnancy spontaneously ends, she might exhibit noticeable symptoms such as unusual vaginal bleeding, throwing up, stomach pain, weight loss and appetite loss. Since miscarriages can be highly distressing to dogs, it's up to you to pay close attention to your dog when she's expecting. Dogs often seem sluggish and inactive after experiencing a miscarriage.

Spontaneous Abortion Basics

If a dog has a spontaneous abortion, a fetus has died prior to the end of the pregnancy. In such a situation, it's possible for some puppies in the litter to be born healthy.


Hormonal imbalances are often responsible for miscarriages. Another typical cause is a bacterium known as Brucella canis. B. canis spreads quickly, particularly among dogs that stay in kennels. The parasite Neospora caninum also sometimes causes spontaneous abortions. This parasite spreads when dogs consume infected animal protein. It also spreads when dogs consume infected stool, food or water. Infection, trauma and inadequate nutrition can bring upon canine miscarriages, too.


Vaginal Symptoms

Unusual vaginal bleeding is a typical sign of canine miscarriage. This bleeding is usually abundant. Colorwise, it tends to be a shade between deep green and black. It usually has a thick texture with pus in it -- but it sometimes can be bloody and thin. If you detect an aggressively unpleasant smell emanating from your pet's vulva, miscarriage could be the reason. If your dog is experiencing unusual vaginal bleeding, you might find that she has expelled a fetus.


Other Typical Symptoms

Other signs that a miscarriage has occurred in a dog include stomach pain, weight loss, fever, dehydration, fidgety behavior, overall malaise, reduced energy levels, diarrhea, vomiting and shifts in behavior. If you observe any of these symptoms in your pregnant pet, alert your veterinarian immediately.


Typical canine pregnancies last for 63 days. It isn't unheard of for dogs to give birth five days earlier or later than 63 days. If a pregnant dog hasn't given birth in a timely manner, she could have experienced a miscarriage. A dog experiencing a spontaneous abortion might release fetal or placental matter that's bloody and dark.


Dogs sometimes have miscarriages that are completely devoid of symptoms, too. This generally signifies that the abortion occurred toward the beginning stages of gestation.

Proper Veterinary Guidance

If you're caring for an expectant dog, your duty is to ensure that she receives proper veterinary guidance and care during the entire gestational period. It's crucial for a veterinarian to oversee the health and well-being of Mama and the growing unborn pups. If you have any questions about how to care for a pregnant dog, your veterinarian can be a helpful guide. Pregnant dogs have strict dietary requirements. If a dog is older, malnourished or ill, her odds of having a miscarriage are stronger.

Always check with your veterinarian before changing your pet’s diet, medication, or physical activity routines. This information is not a substitute for a vet’s opinion.
