Dogs will discharge some red mucus after giving birth. This red mucus is actually what people call postpartum lochia. Female dogs with normal health will discharge it within 5 to 10 days after giving birth. So why do dogs still bleed red after more than a month after giving birth? How to treat a dog that still has red mucus one month after giving birth? Next, let us learn together what causes red discharge in dogs after giving birth.

Dogs will secrete some red blood and mucous membranes from their vulva 10-20 days after giving birth. This is commonly known as lochia, which is a normal physiological phenomenon. But if your dog is still secreting bloody mucus from the vulva one month after giving birth, it may be abnormal behavior. It is recommended that the owner take the dog to the pet hospital for examination in time.

Microscopic examination of vaginal secretions and abdominal B-ultrasound examination can be performed, which can more intuitively see the shape of the dog's postpartum uterus and ovaries, and can also analyze the nature of vaginal secretions. This condition may occur in dogs due to postpartum uterine bleeding, uterine effusion, or uterine suppuration. If the dog does not have serious uterine disease, it is recommended that the owner perform sterilization surgery on the dog after the dog's physical functions recover to avoid serious uterine and ovarian diseases.

The above is about the reason why dogs still have red mucus one month after giving birth. Do you all understand it?
