K-9 officers brighten the day of a girl as she received treatment for cancer at the children's hospital.
Police dog Fix and the 'guy at the other end of the leash' bring comfort and smiles to patients, staff and visitors.
'He's helping put smiles on people's faces,' says the officer who calls himself 'just the guy at the end of the leash.'
'I've had people tell me their kid hasn't smiled for three weeks. The dog shows up and they're aglow.'
