Newby - please help

Hi all lovely people.
I really want to start giving Debo raw. Now, last week he drunk some water from river and now is fighting some bacteria. Didn't have kibble since Wend night and is on chicken -rice diet. My question is when he's stomach get back to normal shell I just start the raw straight away or firt go back to kibble?
I just don't want to make it worst. Now not haveing any dry food, he's body is detoxed so was thinking it would be good idea to go straight to raw?
Any ideas?

Hey! Aw no poor boy! No need to put him back onto kibble, I'd just go over to raw if he's already had a diet change, just don't feed anything too rich initially (liver etc). Hope he feels better soon!

I would start off with raw as well

Thank you. No, will start with chicken breast and some chiken bones.
