I do not think the body will break them down. Ox tail bones are round little disk bones.
I would definately give her some oil to help them slide through. She could have a problem
passing them whole, it just depends which way they are laying at the time of the passage.
She may strain and/or she could bleed some. You do want to keep a watch on her. The
good thing is that muscle stretches quite a bit. I have seen stuff I never thought could
get thrugh, get through. But do give her some oil to help her.
