Robotic Dog

I think a robotic seeing eye dog is a scary idea. I mean, what if it malfunctions? Or how about when it rains or snows? It can't react to real life situations as well as a real dog could - like oncoming traffic or people. The one advantage I could see is that it could have a GPS for a big city like NYC where people walk all the time. If I had a seeing eye dog, I think I'd rather have a real one. As much as I know they can get distracted and eventually it will lead to heartbreak when they pass away, there is so much more of a trusting emotional bond with a real dog.
Besides, who could deny this face?
