What should I do if my dog has ink-like stools?

When a dog has an ink-like stool, the owner should recall if the dog has eaten black food recently. If no black food has been eaten, most likely the dog is suffering from severe intestinal inflammation and is likely to be accompanied by bleeding in the front digestive tract, as the blood goes through digestion and is black in colour when it reaches the back of the digestive tract. It is recommended to take the dog to the hospital for examination and then treat the symptoms.
