Like us in pregnancy every dog is different. I know how you feel though. My girl didn't have a proper season, saw one drop of blood and that was it. Mated her on day 9 and 11 which is unspoken for the breed here in England usually days 16 to 18 are the norm. but in Spain 9 - 11 days is the usual time. She screemed her head off through both mating, but was still up for it when the tie had finished. She also had a 10 minute tie and a 15 minute tie. I'm worried that although she was swollen she wasn't in season I just don't know, but my new boy doesn't bother with any dog, so he must have decided that the time is right as I've had him for 10 months now.
My girl has stayed swollen and is actualy eating for England and Spain although she's only 2 weeks gone.
Fingers crossed for your girl and mine :d
