My aunt puppy walks guide dogs and her job is to show the dog as many things as possible. Trains, buses, kids (she uses mine), parks, shops (the dogs are favourites with the staff in M&S in Birmingham), cafes and restaurants etc. They then got into training. The trainers know which dogs 'want' to work. She had one dog who didn't pass as she didn't 'want' to work. She asked the trainer what he meant by 'want' to work. Apparently they know from the dog whether they will make good guide dogs as they 'want' to please others and 'want' to work. They enjoy it. The dog that didn't make it, wanted to please herself (I don't blame her) and she returned to live with my aunt until she died. My aunt has now walked about 13 dogs and she now understands what the trainer meant all those years ago about 'wanting' to work. She knows herself whether one of her puppies will make it. She didn't think her last dog would and he was too busy looking around and not concentrating. She was right. He now works for the hearing dogs and loves it. She keeps in contact with the people who have the dogs and visits when she can. One was very lively and went to live with someone in Scotland with lots of space and who already had dogs. Another llives by the beach and goes on the beach for exercise. A lot of the people have also kept the dogs when they have retired and then has the new guide dog to play with also. Great lengths are gone to to match the person with the dog. If the person works and is outgoing, they get a dog to match. if the person is more homely etc, they get a more laid back dog. You must remember that most times when a dog is seen - it is working. I know I don't walk around with a smile on my face when I am at work!
