This situation is likely to be a miscarriage, or it may be unstable fetal air or strenuous exercise. It is recommended to take the dog to the hospital for examination to determine the condition of the dog and the fetus. If the dog has a miscarriage, you need to use drugs to help the dog expel it, and feed it antibacterial and anti-inflammatory drugs to prevent the stillbirth from being retained in the body and causing uterine and vaginal infection. In severe cases, pyometra may occur.

During your dog’s pregnancy, you must pay attention to your dog’s diet and avoid strenuous exercise and stimulation.
