How to make sure that your dog is ok after giving birth
Clean your dog with a warm, damp cloth.
Make sure she's clean of any trace of blood, placental fluid, or fecal matter. Good hygiene reduces the risk of bacterial infection following birth.
You may see leaking fluids, called lochia, for several weeks after giving birth. These fluids are natural and normal, resulting from the shedding of your dog's uterine lining.
