Golden Retrievers Maggie, Addie, Luther, Richie and Isaiah are
Boston's hometown heroes - even though they haven't taken up residency.
These five canines are trained 'Comfort Dogs' or what some call
"Therapy Dogs." Their unique role aside from being man's best friend is
to visit various communities in the aftermath of tragedies. And while
they're trained like 'Service Dogs,' this particular group focus on
providing emotional support.
