Dog had spleen surgery. Is bloody stool a post-op complication?

Updated On September 23rd, 2025

Pet's info: Dog | German Shepherd | Female | spayed | 4 years and 9 months old | 77 lbs

Today my Shepherd had surgery. Her spleen was removed and her intestines had folded over themselves cutting off an artery. I have just noticed red blood in her stool. Could this be a result of the surgery or a possible complication? Tia

It may just be blood from the inflammation in the intestines caused by the folding over. However, it could be a very serious indicator of illness, and I would recommend that Holly go to the vet today for a quick recheck. If she were coming into my hospital, I would start with a CBC to check white and red cell levels. I would also review her current medications to make sure they were addressing all of her current issues. She may even need to be hospitalized for continued monitoring. It sounds like she had major surgery! Many dogs will remain in the hospital for 1-3 days after splenectomy to monitor for signs of complications.

    Bright red blood usually indicates an issue lower in the GI tract, while dark or tarry stools can indicate bleeding from in the stomach or higher up in the GI tract. I would let your vet know about the change in symptoms, especially if they are new, sudden, or old ones have suddenly returned. Your vet may recommend bringing Buster back into the vet for additional testing and checkup to make sure the surgery and other treatments are going OK, and may also recommend changing or adding medications as needed.
