There's Belle, who was visiting Rhode Island from West Virginia. She wandered off and spent 35 days at large until Graham found her.
And Brynn, who got lost in a wide tract that stretches across three townships.
"The hardest part is keeping the owners focused," she says. "I keep them busy, I keep them motivated. Their world is collapsing all around them.
"If you haven't lost a pup, there is no understanding just what they're going through."
To keep the owner from becoming unhinged, she often recruits them in the case, spending hours on the phone with them, discussing their dog's personality, habits, what makes them tick.
Then there was Bean, who wandered off in Providence. The search for her led Graham to another lost dog named Hank, who had been missing for nearly five months.
