Maybe this will help.

When I first got Chester I was lucky and I could come home for lunch, so he got fed breakfast, lunch, supper and bedtime.

Soon, I had to stop coming home for lunch and he just got breakfast, supper and bedtime.

Finally I decided all these feedings were rediculous and I just left the food down as I'd always done with every other dog I'd ever had. (Chester was my first puppy)

I don't know what your hours are, but I think she really needs three a day. Can you do breakfast, supper and bedtime?

Bedtime was actually about a half hour before bedtime to alllow for poopie time.
