almost all wormers are ok for pregnant mares, just read the instructions in with them, but don't be skinny with the dose, if you can get a weight tape or other means to calculate the dose, but if it has to be an educated guess it is better to slightly over dose than under dose the makers say you have to give many many times the right dose to do any harm.

another possible cause of the wormy belly look if not worms or a foal is liver inflamation which can also be worm related, or other parasite or plant toxin, if they are not quite as bonny in general as you would think they should be for their diet etc consider getting this checked out if the worm count or foal is not found to be the cause of the teletubbie look.
as to no-one gives away preg mares, you wouldn't be the 1st to find your mare had a surprize brewing no-one expected (except her of course) i had a mare we did not suspect was pregnant because as far as we knew she had never been anywhere near a viable male........

the 3 mares who all had foals can testify he was certainly old enough to bother, thankfully he was a nice full blood arab, so it could have been worse.
