Which of the following is a sign of internal bleeding?

• A. Vomiting blood, or tarry stools
• B. Pale gums
• C. Cold extremities
• D. Bruising

Answer: (A)

Internal bleeding most clearly shows up when blood is found in the digestive tract. Vomiting blood or having tarry (melena) stools means blood has been lost internally through the GI tract, which is a direct sign of internal bleeding. Other signs like pale gums and cold extremities indicate that the animal is losing blood and may be going into shock, but they aren’t as specific to bleeding inside the body. Bruising is more about blood leaking under the skin from trauma and isn’t a definitive sign of internal GI bleeding, though it can occur with heavier bleeds. So the direct clue here is vomiting blood or tarry stools. If you see these, seek veterinary care promptly.
