Answer

Finding dark, almost black blood in your dog's stool can be alarming and is often a sign that something isn’t quite right.

  • Dark blood may suggest internal bleeding in the upper gastrointestinal tract.
  • Possible causes include ulcers, infections, or ingestion of foreign objects.
  • Immediate veterinary evaluation is recommended to determine the cause.

When your dog's stool is dark and tarry, this might indicate that blood has been digested, which suggests an issue in the upper part of the digestive system. This can be caused by a variety of conditions, including but not limited to, bleeding ulcers or a potential foreign body ingestion. While this doesn’t always mean there’s a severe issue, it is important to seek a veterinary assessment promptly to ensure your pet receives the necessary care and intervention if required.

If this is an emergency, please seek immediate veterinary care.
