Hello Elizabeth, I'm Dr. Deb and will do my best to help you today.I'm sorry for these worries about Megan.If she's having a split heat (which is definitely possible), then yes, she could become pregnant during this cycle.Whether or not she has a vaginal stricture which made penetration difficult or whether she wasn't ready yet is difficult to know at this point. A vaginal exam with a speculum may be very helpful in determining if a physical problem exists. In many cases, these strictures can be surgically removed. Even if she is structurally unable to conceive and thus whelp, you could consider surgical artificial insemination. She would, of course, require a c-section to deliver the puppies. I'm not sure if this is something that you want to consider but I offer it a consideration.Of course, things get a little more complicated in terms of timing depending on whether you're using fresh or chilled or frozen semen.The best way to maximize timing would be with vaginal cytology and progesterone testing.I hope this helps. Deb
Thanks Dr Deb. Should I start the timing from the first day of her second bleed?
Elizabeth:You're welcome I'd start evaluating vaginal smears now and every other day. I generally recommend that progesterone levels start being checked when the cytology shows 50% superficial cells. I understand that this can be pricey but you want to maximize the timing. When the progesterone rises above 2 ng/ml, I generally confirm with another test a day or two later to ensure a continued rise. Some bitches will plateau for a few days before starting to rise again.Deb
Thanks. I forgot to ask: could the fact that she was having a split season have accounted for her not seeming ready, either emotionally or physically
So could the pre-mate test that showed that she was ovulating have been wrong. It was not sent off to a lab, but as done by a local large and small animal practice which gives same day results.
Thank you very much Dr Deb That would account for her reluctance. You have been a great help.
