My dog was neutered 2 weeks ago. He had to have a more complex operation as one of his testicles hadn't descended. He has had diohrea for a few days now and today there is blood in it. Is this an urgent matter. I took him to the vet yesterday for a checkup and she said all was good.

There should never be blood in stools, so it is certainly abnormal. Some medications could cause bleeding in the GI tract, so I would stop any medications and call the vet for advice. He should be examined by a vet or emergency vet if additional symptoms develop, such as lethargy, poor appetite, or vomiting.

    Blood in the stool and diarrhea is not normal after surgery, and is likely not related to the surgery. Flash's symptoms could be caused by parasites, stress, change in diet, toxin ingestion, infectious viral diseases, blockage in the intestines caused by ingestion of a foreign body or a mass/growth in the gastrointestinal tract. The symptoms could potentially be a side effect of medication, although if it has already been 7 days since the surgery and this just started, that is unlikely. Please make an appointment to have Flash seen by a veterinarian as soon as possible, as diarrhea and blood in the stool can lead to dehydration and anemia, and can be very dangerous if left untreated. I recommend taking in a fecal sample from Flash to your vet as well, as that may aid them in making a diagnosis.
