If you want to breed your Yorkshire Terrier, then you must be ready to capture the opportunity when it comes. Yorkshire Terriers generally only come into heat twice a year.
My dam comes into heat only once a year. It took some patience waiting for her to show signs of approaching ovulation. But while waiting for that time to occur, I started my search for the appropriate sire. My search included going to dog shows, going through Yorkshire Terrier breed specific magazines and online resources widely used by breeders, but most importantly asking the opinions of breeders for information on possible stud dogs with blood lines and physical characteristics that may be suitable for my dam.
The female shows first sign of ovulation with a swollen vulva and then followed by a bloody looking discharge from it. The discharge continues to and becomes lighter and clearer approximately eight to ten days. The objective is to ensure that she is in the correct stage in her estrus cycle.
As soon as MySP showed the first sign of a swollen vulva, I gently swabbed her with a moist cotton at least twice a day checking for a bloody discharge. I marked the calender as Day 1 the first day of bloody discharge. I likewise marked Day 10 through Day 17.
It is during the period days 10 through 17 time frame when the female can be successfully bred. During this time, she will exhibit standing behavior. To "stand" means the female will allow for the male to breed her. (If you gently rub the base of her tail she will literally stand erect with her tail up).
During my search for information, I found the ovulation chart below understandable and was readily available from an online resource provided by the Hilltop Animal Hospital in Illinois from their web page at http://www.hilltopanimalhospital.com/ovulation%20graph.htm
