Which gum color indicates a possible oxygen exchange problem with the lungs?

• A. Pale gums
• B. Pink gums
• C. Blue gums
• D. Red gums

Answer: (C)

Mucous membrane color is a quick clue about how well oxygen is getting into the blood. A blue tint to the gums, or cyanosis, signals that oxygen levels are low and the lungs aren’t exchanging gases effectively. This reflects a potential oxygenation problem requiring urgent attention, since tissues aren’t receiving enough oxygen. Compare that to pale gums, which point to poor perfusion or possible anemia; pink gums, which are generally normal; and red gums, which can indicate inflammation or irritation. If you see blue gums, evaluate breathing effort and rate, and seek veterinary care promptly, as cyanosis can indicate a serious respiratory or cardiopulmonary issue.
