Through the last six years of his life, Parley Nichols, 81, never left his Hartville, Ohio, home without his dog Lady. The two were best friends, soul mates and constant companions who took care of each other. So when Parley, who had developed dementia, went missing on April 8, it was no surprise that Lady, his 6-year-old golden retriever that he bought as a puppy, was also gone.
