dawnandjr Just to give an update. Her numbers were obviously good based on the size of her belly. She has about 6-7 puppies. Will confirm with x-ray next week. She did have some unusual bleeding though. She bled continuously and heavy up to 41 days post ovulation. Did about 4 ultrasounds and blood tests. Bleeding has stopped at this point and her blood work is back to normal. Ultrasound still good.

gsdsar The surge happened sometime in the 6 days. So f you got the AI done quick you probably caught her in time!!! Good luck!!! Puppies are exciting!!!

dawnandjr Test on Tuesday was 14.2. Will do ultrasound to confirm pregnancy shortly after valentines day.

dawnandjr Okay, so first test last week Wednesday, 1.7. Historically she rises very slow. Ha, bitches. Test yesterday, Monday, 13! Doing AI today. That was only a 6 day difference. Hopefully she just ovulated and eggs still viable. I was really hoping to get more numbers out of her this time to predict the surge.

gsdsar You are right. 5 is not the number, but once they start rising it's considered the surge. Some bitches will go from 5 to 12 to 20 in 3 days. Generally if you are trying to time an insemmination you start planning for shipment to fall about 5 days after that initial surge. There is no way to know what the exact number will be in advance. But if you wait until the progesterone hits 20, THEN you ship, you are more likely to miss her fertile period. That's why regular testing and knowing when she surges is important.

dawnandjr gsdsar, thank you for your answer. But unfortunately its not as easy as that. This misconception being that bitches ovulate right at 5.0ng/ml. Was looking for some good numbers from others that test with progesterone to see how high they wait to AI. When talking with the coordinator at the vet she said some bitches they will wait til they get a 20.0ng/ml. I am thinking I am going to do my first test tomorrow, since we are coming up on a weekend. That way if she is rising, I could get semen shipped on Friday to inseminate on Sat. I am off on Monday (holiday), will have to see if the lab is open and draw again on Monday. Then with those numbers, decide if we need to do a second insemination.

The LH surge is timed by watching the progesterone. If you are shipping semen, then knowing the best day to breed us important for collection and shipping. So you get progesterone levels every 2-3 days. Once the progesterone spikes to over 4-5, then you generally know that the LH surge is imminent. So you schedule the insemmination 4-6 days post surge.

If breeding naturally, then you really just have to wait for the male to really show interest and the female to start flagging and be receptive. But if you are shipping or doing a surgical AI with frozen, timing is essential. Especially with frozen, since you really only get one shot.

Liesje Holland, some places have a longer turnaround so it's not as easy as breeding at a certain level. My male missed a breeding this way. The breeder wanted to a shipped chilled semen AI, so we had everything lined up with my repro vet. In fact I was on vacation so my dog sitter had agreed to bring my male for boarding at the repro vet the day the breeder called for the collection, and they could collect him while he was there with my permission. The breeder brought the bitch in for progesterone testing. The next day the vet called with the result but the numbers showed she needed to be bred the very next day. Unfortunately that was 4PM our time, there was no way for my dog sitter to get my dog into the repro vet for collection in time and even then the shipping would have to somehow go in less than 24 hours. This was actually not the first progesterone test the breeder had done, she had been tracking the bitch's progress and that is how she guessed what day she thought my male would be needed. Well, the bitch simply sped up faster than anticipated and we missed our chance. It's more complicated when you are waiting for results and/or doing shipped semen which requires another 1-2 days shipping and a good vet on the other end to implant. Weekends can be a nightmare. My repro vet recently got their own machine so they can turn around results as fast as 2 hours, but since I own the male end it doesn't really help.

holland I am not a breeder so really don't have a clue-but isn't the whole point of progesterone testing that when you get a certain level you breed the dog-my friend used to have it done at Cornell-they are awesome-love Cornell
