This could have been a story with a tragic ending. Cocker spaniel Asher was on the brink of being put down after going through eight different owners who rejected him because of his naughty behaviour.
But then Dr Claire Guest met the troubled hound, and after looking into his eyes, realised she had met a kindred spirit. Claire is the co-founder of Medical Detection Dogs, a charity at the forefront of research into dogs’ ability to detect the smell of human diseases and save lives.
She saw that Asher's main issue was that he just needed to be kept busy, and most importantly, displayed a strong motivation to help. So she decided to adopt the four-year-old pooch and see if he could be trained to work with the charity.
