Proestrus ( 7 - 9 days) (Week 1) Ovarian follicular development Vulva swollen . Bloody discharge Attracted to male, but does not mate. Anterior pituitary has been secreting follicle stimulating hormone (FSH) – growth of follicles on ovary. Follicles secrete estrogens – proliferation of glandular tissue in the uterus and vaginal mucosa. capillaries in the uterus and vagina leak some blood and the dog has a bloody vaginal discharge.

The vulva swells during proestrus and pheromones are secreted that drive males into frenzies and on a humid night will attract them from miles around. The female may act moody during this stage to both people and other dogs, swinging from affectionate to "snappy" and seem to like to "tease" the males cruelly: they'll lift their tail to allow a sniff, but will bite the male if he tries to mount .
