The heat cycle lasts approximately 2-3 weeks. I highly suggest you spay your dog if not planning on breeding her. She will live longer and be much healthier if you do. You will cut down her risks of mammary tumors, infections of the uterus, pyometria, perianal tumors, etc. She should be spayed when out of heat.
