What kind of physical testing do guide dogs undergo?

The exact testing is up to the individual program training them. Each will set up their own criteria. However, the test would include working in public navigating around common obstacles, including low-hanging obstacles and traffic.

Health testing would include an evaluation of the dog's hip structure by x-ray, chest x-rays, hearing tests, CERF (eye test), thyroid function, and cardiac function as well as a full blood panel to check overall function of internal organs.
