I have just called the vet again, and mentioned the photo and ventral rupture and he said he would definatly be here in the morning, She only looks like the white horse, not the others. It may be that the foal has dropped into a strange position, but I am surprised she hasnt foaled and want him here whatever. Better to be safe than sorry.
My farrier/trainer just felt her all over, not internally as he didnt have any gloves. He felt the "tire" shape too. I have tried to call him but he no answer.
"he no answer" ???? too much land before time movies for me~ LOL
I was hoping he would come sooner, but he didnt seem to think he needed too. I hope that if she does foal, she is ok. She has been laying down a lot and is "off" her hay completly.
OK - Your vet is an informed person on the urgency of the situation, and I'd trust his judgment that tomorrow is soon enough.
There were common sense advice tips on things to do for her, to let her be quiet, keep her movement to a minimum, and it wouldn't surprise me that she wants to lay down.
