My little baby had similar symptoms which turned out to be colitis. She had bloody running stool with bright red blood and it it was very dark like tar almost.
Per the vet, I gave her bland food and after several days it cleared up. It also took several more days for solid poop to form. At first it didn't seem like it but each day, her pooped eventually did get solid.

I now know certain foods will trigger her colitis and on occasion even her regular diet would trigger it. I finally found a limited ingredient food for her and she hasn't had a bout of colitis since
