Hi and welcome to YT.
She should be okay for those 8 hours with the set up you have.
Poppy sometimes eats her poop too, I read in a yorkie book I have that this is common with pups and causes no harm.
Sometimes they do it because they are cleaning up after themselves or because they are plain hungry and its appealing to them.
The book said that they usually grow out of this behaviour at around 1 year old.
