Hi there and thanks for your question! I just have a few questions before I answer:
OK, thanks for that info!
We often get questions about dogs who have blood in their stool and usually the owners are quite worried. However, with dogs, it only takes a little bit of inflammation in the colon to cause bleeding, so it is very common to have bleeding along with diarrhea.
The most common reason for inflammation in the colon is a new food or treat or sometimes stress, but often we don't find the cause.
As long as your dog is bright and alert I would not be too worried. The best thing to do in cases like this is to give him a period of 24 hours with no food (water is ok) followed by small meals of chicken and rice. Then, after a couple of days you can gradually add back his regular dog food. Make sure he has no treats or table scraps in this time.
If he is still not feeling well in 24-48 hours or if you think he is very uncomfortable then a vet visit may be in order.
I hope he does ok!
