Dogs generally bleed for several weeks after giving birth, according to The Daily Puppy. However, the bleeding should only occur around the vulva. The dog may also leak a reddish fluid, called "lochia," for weeks after giving birth.
Lochia is odorless and should not have pus in it. When lochia has a foul smell or pus, it indicates infection. While bleeding is normal after birth, if a dog is bleeding a large amount of blood or fresh blood clots, she may be suffering from postpartum hemorrhaging, according to High Street Epping Veterinary Clinic. Dogs that exhibit symptoms of abnormal bleeding after birth need medical attention to avoid further complications.
