My dog has black, bloody stool but is energetic. Is it serious?

Updated On September 23rd, 2025

My dog had black, tarry stool w/ some blood yesterday. Her appointment will not be until tomorrow in the morning. She is a Chihuahua/Yorkie mix who is 2 years old. She still seems energetic but she doesn't have much of an appetite. I just have to ask...will she make it in time?

If she is still energetic and not vomiting, doesn't have abdominal pain, and her gums are nice and pink (versus pale) then most likely she will be ok until tomorrow though none of us can predict exactly how disease will progress. Signs she should go to the emergency vet would be pale gums, weakness/lethargy, repeated vomiting, abdominal pain, difficult breathing/excessive panting. If these occur or if she is having repeated diarrhea she should go to an emergency vet.
