Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Good question. This can vary slightly from dog to dog but typically the first part of the heat cycle is called proestrous. It can last up to about 10 days during which bleeding is noted from the vaginal area. I encourage you to spay your dog unless you are going to breed her. Mammary cancer is directly correlated to estrogen in dogs and every heat cycle that the female goes through raises her risk of mammary cancer later in life. Also, 30-60 days after each heat cycle, a female dog can develop a life-threatening infection of her uterus called pyometra. Spaying helps both of these issues plus you will never have to experience her going through another heat cycle. Please watch her closely during her heat, never let her outside by herself. She will be attracting male dogs during this time. Good luck
