Drinks a lot, good temperament, vet can not re-check stool until after 7 days. what should we do till then?

Answer
I am not sure there is much you can do.  You could try a bland diet.  If a dog is having trouble keeping anything down or continuing diarrhea try this out of the manual I have from a large, knowledgeable dog guide school.

Bland recovery diet for dogs.

3 parts cooked rice, one part boiled hamburger or chicken, or cottage cheese. I think you can substitute boiled potatoes for the rice. Once in an emergency, we bought a plain baked potato from Wendy's.

This is meant for short time settling a dog's digestive tract. It is not the complete and balanced diet they need long term. I have seen it work.

If it doesn't firm it up, likely it will need more parasite remedies from the vet.
