Dog stool colour triage

Black stool in dogs: what it can mean

Black or tar-like stool can be more concerning than ordinary colour variation. It should be judged alongside energy, appetite, pain, medications, and whether there may be blood.

What to check now

  • Check whether the stool is truly black and tar-like or simply dark brown.
  • Note any vomiting, weakness, pale gums, pain, or appetite change.
  • Consider recent medication, diet changes, toxins, or foreign object exposure.

When dark stool is urgent

  • Emergency vet now if black stool appears with weakness, collapse, pale gums, or breathing trouble.
  • Call a vet today if dark stool repeats or your dog is not eating normally.
  • Seek urgent advice if dark stool appears with vomiting or suspected toxin exposure.
