Postpartum lochia is rare in dogs, so you don't need to worry too much under normal circumstances. Postpartum lochia is the tissue falling off the inner wall of uterus and the blood remaining after delivery, which usually lasts for several weeks or even a month before it is completely discharged. If the dog still has lochia more than a week after delivery, you should pay attention to the following points:

1. Observe the physical condition of the dog. If you have symptoms such as loss of appetite, continuous increase or decrease of body temperature, and breast pain, you should seek medical attention in time;

2. Pay attention to the dog's liquid intake and keep enough water and nutrition, which can increase the rate of postpartum lochia discharge;

3. Avoid excessive exercise. Dogs need proper rest after delivery, which can reduce the harm to the body and help the discharge of lochia;

4. Regularly observe the color and quantity of lochia. If lochia gradually subsides and continues to decrease, it means that the dog's condition is gradually improving.

In short, in the case of postpartum lochia, we should observe the dog's physical condition in time, adjust the diet and rest appropriately, maintain a good attitude and give necessary care. If the dog's condition is obviously abnormal, you need to seek medical attention in time.
