I am cross posting this just to try to get some answers to quell my nerves and help me know what to expect...

We have an imported Hanoverian mare who suddenly started "puffing" last week and we realized was not sweating (our first experience with anhidrosis). We then found out she had a bout with anhidrosis about 4 years ago and at the time was in foal, and lost the pregnancy presumably due to it, which went untreated they guessed about a month since she was apparently turned out with many other mares in a large field.

The mare is not quite 60 days in foal at this time (bred June 3), and we're doing everything we can to keep her cooler - of course we just had three days of official highs of 105 so she was still lightly puffing despite an ac unit blowing in her stall, sponging, fans, etc. Luckily it has cooled to about 88 but still humid, and she is still in with her current foal under the fans and ac unit.

What are the chances she will lose this pregnancy? I have searched and searched online but can't find anything related to pregnancy loss due to anhidrosis. We are giving her, supplements, beer, and electrolites in hopes she will start up again. She was out all last summer (with shelter, same as this year) but did not have any problem. She was in foal but not nursing, whereas she is nursing too this year and it's been exceedingly hot. Also, if they go through winter, will she start up again in the spring?

Thanks for any help or advice you can give!!!

It's almost impossible to predict whether she will lose the pregnancy or not. Overheating during very early pregnancy (particularly <8 days) has been demonstrated to increase pregnancy loss significantly, but after that point - or at least once fixation, heartbeat and placentation are initiated respectively - there will probably be different responses.

Essentially, all you can do is wait and see. Addition of progestin supplementation may be beneficial and should be discussed with your vet.

Thanks so much for your reply. Just worried to death since she lost a previous pregnancy to this, however, the owner admitted it went on probably a month before she found out (she was boarded and out in a huge broodie field). Hopefully we caught it early enough this time and are making enough progress in cooling her to prevent it.

Sorry for the double post, just so wound up about it and looking for any info - seems very little on preg mares with the condition and the resultant effect.

Be aware that you are in the time frame (~90-150 days) when the pregnancy is likely to have fallen over the pelvic brim and into the abdominal cavity and be out of reach of the ultrasonographer/palpator. It is not uncommon that errors are made with a "not pregnant" diagnosis at this point by those perhaps unaware of this.

While your mare may have indeed lost her pregnancy, I merely post the above as a caution so that you absolutely confirm the status before doing anything that might threaten a pregnancy - I am thinking particularly of uterine swab/biopsy or the use of Prostaglandin F. You might want to check again prior to that point, or you could even check now using a blood or urine test for estrone sulfate or total estrogen levels (there is a stall-side assay that is discussed elsewhere on this board called the "Wee Foal" test kit - do a search for it using the search feature that is linked at the top of the page).

Thanks, Brittany and Jos. Our vet (extremely good repro vet) did ultrasound her, and this was on Sept 1, so a little while ago. However, she would have been about 90 days at that point. She said that her uterus was empty. I wasn't present - not that it would have mattered... but do you think it still could have been missed? This IS a large, 16.3h Hanoverian mare. We won't be messing with her until springtime, so I guess at least at that point it should be obvious ;) Thanks!
