Blood belongs in blood vessels and has no business being anywhere else. That includes external bleeding, internal bleeding, blood in vomit or blood in feces.
Blood in your dog’s poop does call for veterinary attention. It may or may not be an emergency.

When is it an emergency?
The urgency mostly depends on the amount of bleeding and presence or absence of other signs.
Diarrhea can aggravate the gut lining enough to cause small amounts of fresh blood in the stool. You need to understand that this happens because there has been enough damage to the gut tissue to cause it to bleed. Then the question remains what is behind all the damage. Is it an infection? Parasites? Is it an inflammatory disease? Trauma? Foreign body? Is blood not clotting properly? Or even more serious things such as cancer?
Just because the stool might be solid doesn’t mean the reason for blood on it is not serious.
See a vet
The thing is that you have no way of knowing what the cause is. If you find blood in your dog’s poop, you absolutely need to see a vet.
If there is a tiny amount and there are no other serious symptoms such as signs of pain, vomiting, lethargy etc, you might be able to wait till the morning or next day to see your vet.
The more blood and the sicker your dog appears, the more urgent it is they get medical attention. If your dog is a young puppy, also don’t wait at all.
If you found blood in your stool, would you seek a doctor?
Same should apply to your dog. I recommend higher caution with a dog because unless like with yourself you can’t always know how your dog is feeling exactly. You may or may not be able to read signs of pain, weakness and other serious symptoms.
Things can get worse fast
Many of the potential causes might start with a bit of blood and blow up in a disaster. Foreign bodies can cause severe injury to the intestine and even lead to sepsis. A young dog might have parvovirus infection. Your dog might be suffering from hemorrhagic gastroenteritis.
Always err on the side of caution.
