Update from facebook :
Bit-O-Blue Minis Checked records again. Sugar was bred May 18, 19, 28, 30. In July vet determined she was open. Did lutalyse 3rd week in July. Bred every other day July 30 through August 8. No idea if she could have caught in May -- what would lutalyse do to a pregnant mare? Abort the foal, right?
Lutalyse is a hormone you give to horses to make them ovulate . Isn't Google wonderful :wink: LOL
