It may be because of pseudopregnancy. Pseudopregnancy, also known as pseudopregnancy for short, refers to a mature female dog that has undergone physical changes and behavioral changes similar to pregnancy, regardless of whether it has been mated or not. For example, there is a tendency to breastfeed, or to build a nest for the cubs, but the baby does not give birth when the due date is reached. False pregnancy is most common in female dogs 6 to 8 weeks after estrus. At this time, she will have this symptom due to hormonal imbalance in the body.
