A very common reason for having bright red blood and soft stool is a condition called colitis. This is an inflammation in the colon that commonly results from a change in diet or a stressful event. You could start by feeding a bland diet of plain boiled chicken breast and plain white rice. You could also add fiber in the form of canned pumpkin puree. As long as he is acting normally, you could see if just the bland diet will resolve it. If you see other signs such as lethargy, vomiting, poor appetite or diarrhea, I would strongly recommend taking him to a veterinarian for evaluation. They may recommend a fecal exam to look for parasites or recommend x-rays and blood work to look for the underlying cause.
