Pls help me understand these progesterone numbers - Page 1

Day 1 Brown blood - faint
Day 4 - more faint bleeding - prog test done and levels show no activity 0.9 nmol
Day 12 - Prog 5.2 nmol
Day 15 - Prog 4.4 nmol

Bleeding this heat was was very faint and only brown - not usual red
Not very much swellling and not much even now on Day 17
Male dog not very interested - female quite aggressive toward him Day 13

So...why the small drop (or no rise) of Progesterone between Day 12 and 15.  Is this a hallmark of a SPLIT heat?

How would you proceed with regard to testing?

kmaot,

There is a possibility that the lab results are incorrect. Did you repeat the test again? You are thinking that the progesterone should continue to rise, and in most cases, it does. Whether this is some anomaly or not is not possible to say without additional lab results. What does the female say? 

Incorrect??  That would be unfortunate.  Very unfortunate.  We are getting tested tomorrow but results will come through on Wed. 

Now...to add to the mix...the female is fighting some bacteria as a swab showed both staph and strep.  She is finishing the antibiotics now.

The female is a maiden and does not flag and never has. 

Smear showed a "mixed bag" on Day 12  - not necessarily indicated ovulation was happening.

Sounds like you have more troubles than just what the real progesterone value is.....

Good luck.

Perhaps Hodie.  The infection is cleared up however.  Could be a red herring.

 The infection is the priority to clear up, and this may require a longer period on antibiotics than 7 or 10 days, probably 14 to 21 days.
It is possible for the progesterone to continue for a period at the level of 4 or 5 and then to take off, you need to test every 2 t.o 3 days. I have one female who doe sthis, and is usually ready for mating  (around 30) on her 27th to 31st day, and she has litters

  The LH surge is at about 2ng/ml = 6.36nmol/l then intern comes ovulation. On tell the reach the LH surge they can go back down but once they reach 2ng/ml they should go no where but up. You need to do another test for sure. I would do another test on day 17 or 18. It could be that she well not ovulate as well.   I had a female a few years back that was 1.1ng/ml  3 days later  1.4ng/ml,  3 days later 1.7ng/ml,  2 day later 1.3ng/ml.  She never did ovulate that cycle.

Went to the vet - no sign of infection BUT we got another 7 days of antibiotics as insurance.

She is quite "loose" down there.  She is now bleeding in a normal fashion - red and more heavy - not brown and faint.  She was also 80% cornified.  I am awaiting the prog numbers today.

This was a bit confusing as I didn't think she would be so cornified with that much bleeding. 

I STILL don't know however if that was what one call a split heat OR if she was just in proestrus for almost 3 weeks. 

Thanks for your input. 

UPDATE - full bleed last 2 days.  BUT progesterone is only 1.0 nmol as of yesterday.  So it has dropped beffore any LH surge.

So gang - is that a split heat. Some symptoms - not a regular bleed - no interest in males - prog numbers rise but then drop - and finally a full (normal for her) bleed with red (not brown) blood.  We are now on about day 19 or 20 from the day I first noticed a bit of brown blood.

Hell, I don't know. Probably a split heat. Mine have had them a lot in the last year or so. Makes it tough if you are shipping or traveling a distance for the breeding. All it takes is a climate/temp fluctuation, a little stress, to knock 'em right off their cycles.
Damned bitches don't read the books, do whatever the hell they want to do, don't bother to let us in on the plan!
