I went up to New Holland over the weekend and came home with a rescue :-)
She's a 12 y/o Belgian mare, Amish "broke to work", skinny (2.5 BCS), but not in terrible shape physically - she does have breeding injuries though. She has bite marks all around her withers and right shoulder and her vulva was swollen. Bite marks looked to be a week or two old.
Had the vet out of course, but she is very skittish with anything new, and blew through a lot of sedation (oral and IM) - we were not able to pull blood at all.
Vet wanted to just give her a shot of Lutalyse to abort anything that's in there - but here's my concern: what if she had been bred prior to this past incident and is further along than 15 days or so? I understand from lots of Googling that Lutalyse is effective at aborting up to 34 days, not terribly reliable 35-90 days and hit or miss after that - what I cannot find online is: if Lutalyse does not cause an abortion in a mare, does it cause any harm to the fetus?
Our plan, assuming that we could get blood, was to run the blood for a preg check (no vet has volunteered to palpate 17.2 hands of nervous lol), and if it came back positive, we would keep the foal (vet said the blood test is sensitive after 3 months, and I don't really want to abort anything much older than that), and if the test came back negative, we would just give her a shot of Lutalyse to abort any early embryo that may be in there.
Thoughts? Suggestions? We could just give her the shot without a preg test, but I am concerned about damage to an older fetus...
