I get confused about the difference between a round belly and the 'V' shape that a mare is supposed to make before she foals.
Ace here should be due, overdue even, and she seems to be making little progress. She threw a small udder back at the start of March, which goes up and down, but has never filled properly.
She has sunk in by her tail head, and feels looser there, but the vagina itself hasn't loosened much.
From these pics do you think she is making progress?
