I got the train to Oxford yesterday morning and these two got on. They sat down and the dog proceeded to wrap himself around his owner to make sure he knew he was there. He barely moved except for when the announcement was made for a stop when he proceed to prompt his owner. They were getting off at the next stop so he told the dog to wait for the next one. As the dog felt the train slowing down for the correct stop he got his owner ready by standing up and moving him to the door. Mind blowing stuff really. It must be reassuring to have a companion like this with you all the time if you have issue with your sight.
In my opinion everyone should support Guide Dogs for the blind.
