A little late and a dollar short I'm sure but:
pedyalyte (sp) for dehydration.
find out what kibble mom was being fed but it in the blender and grind it to a fine meal mix it with a little goats milk (found in the condensed milk aisle)
I used to show Wire fox terriers years ago and this is what I started my puppies
on at 5 weeks. My babies were still having a morning and night nurse from Mum
at this age with full weaning at 7 weeks.
I'd also buy the jar baby chicken (not meat from a baby chicken
it's a long storyLOL) from the baby food aisle. Have some baby rice cereal on hand too
the box one you can mix with pedyalyte.
Keep her warm and have fun!
