3 month old pup was doing fine until two days ago when I noticed two piles of diarrhea feces (no blood). He went from eating, eating half to not eating @ all. He been on raw for about a week and seemed to love it. I eased him into the raw feed before I just switched him over. I thought he might have coccidia so I gave him some corid (1st dosage yesterday) and gave his second one this morning. He is updated on his shots, gums are pink, but he has diarrhea so i think it might be coccidia/giardia or some kind of bacteria infection. What do you guys think and what would you do? Any help/advice would be appreciated.

Thanks in advance,
