I have a 2 1/2 year old Border Collie bitch. She is checked and healthy and I took her to stud 5 weeks ago. Since then we have had an extremely affectionate little doggy (even more than usual). She has been asking for breakfast (something she stopped having at 5 months old). Her nipples have pinked up. She had some morning sickess a week or so ago. She has a slight vaseline-like discharge, which is clear. She has been a bit more, how do I put it, "guarding" than usual, barking at noises outside in the garden and patrolling more than normal. To me, these are good signs that she is actually pregnant. However, I took her for an ultrasound yesterday and they couldn't find any puppies.
Pepper has had 2 seasons before, at 11 1/2 months and then 11 months later. This heat came after 9 months, so she has long, irregular heat cycles. She only has a short season, though. The first was 7 days coming and 7 days standing. The second was 6 days coming and 6 days standing. Knowing this, when I arranged the stud I persuaded the stud owner that days 8 and 10 would be better than her recommendation of 11 and 13, given her history. As it was, she was 5 days coming and 5 days standing this time around, going off on day 11. She went to a tie both times, for 20 minutes each time.
She has had false pregnancies with both of her previous heats, but the signs were not quite the same as this. Additionally, with both of them she had her "puppies" well before a real pregnancy would have ended. About 3-4 weeks first time, around 5 weeks the second time.
Not very reassuring, when I was waiting at the vets a woman came out of his office with a Newfoundland who had had 2 scans where they did not find puppies. An x-ray had just confirmed that she was in fact 8 weeks pregnant, although I didn't hear how many puppies - presumably a small litter. This makes me think that maybe the equipment or the vet are not that great.
So I don't know if anyone can answer the questions, but with a wealth of experience here maybe you can tell me. What are the chances of Pepper not being pregnant after 2 tied matings? Could the length of her heat be a problem? Could she be less far along as a result, maybe only 4 weeks (having read about heat cycles in depth, and that the eggs have to mature, the sperm can survive for up to 9 days, etc, etc)?
I guess I will just have to wait and see, as I am not really willing to keep spending money on scans at a vet I know to have missed a pregnancy, albeit a presumably small litter in a large-breed bitch. Any answers will be gratefully received, however.
Many thanks.
