or perhaps not...

is there any difference, other than it being easier to eat, in feeding food dry or soaked for 20 mins?

I have been feeding the pup (nearly 5 months) Acana Puppy and Junior. She's been on it for a few weeks now with no problems. I've always soaked it though. Yesterday I gave her half soaked and half dry and today just dry and today she has very runny poop. Diahrea. She's been wormed and had her popped tested for parasites, the only thing that's changed is the fact that the food is now dry.

Can that cause it?
