I recommend to have Izzy examined by her veterinarian today. Dogs who are in heat will have a bloody discharge that is usually very light colored. Infections in the uterus can be severe and even fatal if not treated quickly so it’s best to have her checked for this today. Cancer and vaginitis are also possible. Best of luck and please feel free to post any additional questions.
