What does Black puke mean? Your vomit may appear black if the blood has been oxidized by the acids in your stomach. The iron in your blood turns from brown to black with time. Since the blood is no longer bright red, it means that the bleeding has either stopped or is only happening in a small amount.
What should I do if my dog is vomiting black? If the bleeding is in the gastrointestinal tract, it can cause problems which are hard to treat, especially without surgical intervention.
