Hi, Sarah,
Rather than answer your question here, (the short answer is it depends upon the stage and the severity of the infection), I suggest that you look up 'Coccidia' on the googol site. there are many excellent articles which i could noy tpossibly summarise here.
We are in the UK, where we see very little coccidiosis in dogs. Are you in the US? I know that the situation is different there.
