They are pretty accurate. I've never bothered because the vets have to buy large lots of them, they usually don't have a need for them, and in another 10 days you'll know for sure. I'm not big on x-rays for a pregnant bitch. Ditto ultrasounds. I don't want a healthy bitch who might be pregnant making unnecessary trips to the vet. (Especially when I'll have my answer in another week anyway.) What I WOULD do IF this is a bitch who has had problems conceiving before is to test progesterone levels. If they don't remain high enough to sustain a pregnancy even if the bitch was pregnant, she'll reabsorb.

A friend has a GSD at 29 days post breeding who tested negative with a blood test from the vet. Since the bitch is acting different, and they think the nipples are slightly changing, I told her I would ask around to see how accurate these blood tests are?? I think it's early, and I also think if the blood tests were fairly accurate, many more of us would use them. Any comments? Thanks!! Bonnie Dinsmore **************Wondering what's for Dinner Tonight?
