A seeing-eye dog, or any dog trained to guide the blind, cannot tell a red light from a green one. When it leads its master across the street, it watches the traffic flow to tell when it is safe to cross
Met a blind couple during my last visit to Baguio. They are eking out a living working as masseurs in a massage clinic. The man said, he turned blind when he was 10 years old. Out of curiosity, I asked them how they manage their movements around. I told them about the seeing-eye dogs, and how they help people with impaired visions. They said, they never heard of such a thing. The chance discussion did not end there. They're very eager to learn more about these service dogs.
Nowadays, blind individuals are enjoying more independent lives with the aid of seeing-eye dogs. These dogs can lead their blind owners around their homes, neighborhoods, and even down a busy sidewalk in a big city. Seeing-eye dogs are able to alert their owners of dangers, curbs, stairs, looming obstacles and more. They are able to help to retrieve items their blind owners may need.
