Breeding my two Bostons

Question
My male dog really dont want anything to do with the female, she keeps trying to mount him and he get mad,and grows, does this mean they are not going to breed?

Answer
Hi Melissa.  Is your female in heat, or is she just play mounting?  How old are your dogs?  I'm assuming that this is your first attempt at breeding these two.

It has been my experience that the male dog will sometimes ignore the female until she is in the right stage of the cycle.

The heat cycle, normally latest for approximately 21 days and consists of four stages as follows:

Stage One - Proestrus Stage:   This stage begins with the appearance of vaginal bleeding and normally lasts between 4 to 9 days.   Male dogs will be very interested in the female; however, she will not be interested in them, and will actually bite and reject a male if he advances.

Stage Two - Estrus Stage:   The vaginal discharge is more yellowish than bloody. Ordinarily, this stage lasts for 4 to 13 days, and is the time the female will accept the male and actual mating can occur.  

Stages Three & Four - Metestrus and Anestrus:   These final 2 stages are periods of ovarian activity, but with no significant outward signs. False pregnancies frequently occur during metestrus.

Thank you for giving me the opportunity to answer your question, and please do not hesitate to contact me again.  sincerely, Penny D.
