Ruby, a 1-year-old white Siberian husky, can tell the Meals on Wheels van has arrived before her owner, Candace Robinow, can. Though driver Walt Johnson has just pulled up, Ruby has already run to the front door, eagerly awaiting him. The drop-off includes much-needed meals that help Robinow survive. But this visit is special: Johnson is also carrying a bag of dog food for Ruby.
