i have a litter of 7 week old pups who over the last few days have had runny poo's, i feed them on minced chicken mixed with pedigree small bit mixer, they were wormed and vet checked last week and everthing is fine with them, what do you think i should feed them to dry there poo's up?

Some rough bran mixed with their food, looks a bit like saw dust and can be bought from the petshop. HTH.
