Dog pooping blood?? - dog poop blood not parvo

My almost 2 years was Jack Russell / Papillion mix, the blood of the shit. It began about 3 weeks. It has also steadily risen, food, etc., which took her to the vet immediately. They said it was testing a little dehydrated, and did, and ruled out parvo, which will be noted and no blood in him, everything went well, said a change to your diet to sweet foods. Well, it took time to make your pool, solid, and the return to normal, he did. It is now done with its medicines, and last night refused to eat again, this morning saw blood in your stool, we want to bring him to the vet, but what could be wrong. I will not say it's good.
