What colour do guide dogs wear?

• A. Yellow
• B. Blue
• C. Green
• D. Burgundy

Answer: (A)

When a guide dog is working, the harness or vest worn by the dog communicates to people nearby that the dog is in service and should not be distracted. Yellow is used because it is highly visible and easy to spot in a variety of environments, from busy streets to indoor spaces. This visibility helps pedestrians, drivers, and staff recognize the dog’s role quickly and give it space to focus on guiding. While some programs may use different colors, yellow is the most widely recognized standard for guide dog gear in many educational contexts and public campaigns, making it the best answer for what color guide dogs wear. The other colors are not as commonly used as standard working gear, so they don’t convey the same universal signal.
