The pattern of reproduction of the domestic female dog is remarkably different in several aspects from those of the farm animal species. The female dog, bitch is a spontaneously ovulating animal characterized by prolonged preoestrus and long behavioral oestrus. She is monestric because in each breeding season she has only one oestrus which is followed by a prolonged period of anestrus. Another characteristic of the bitch is the frequent expession of postovulatory pseudopregnancy following a nomated oestrus or a mated oestrus not resulting in pregnancy. To be known endocrine aspects of bitch reproduction ensure predicting of the ovulation time rapidly and reliably. In connection with predicting of ovulation time ensure determining of insemination time and so improving of fertility. Therefore, recently studies have been focused on particularly hormonal changes associated with the oestrus cycle
