NEWBURYPORT – The “chief dog officer” of Seacoast Labradors, Courtney Breen, will visit WJOP’s “Morning Show” on Friday to discuss service dog training.

Host Mary Jacobsen will interview trauma specialist and Breen, a psychologist with a Ph.D., about how she trains service dogs to detect scents.

Breen was inspired to found Seacoast Labradors after her work as a mental health responder following the Boston Marathon bombings. She noticed that her own diabetic alert dog was incidentally providing relief to trauma survivors.

Subsequent research by Breen showed that dogs could be trained to detect high levels of the stress hormone cortisol. Scent-based detection of high cortisol levels enables trauma response dogs to help lower those levels.

For her “Books from Off the Beaten Path” segment of the radio show, Melinda Everett will continue her “biography of biographies,” bringing listeners up to contemporary times.

The “Morning Show” airs Friday from 8 to 9 a.m. on WJOP (FM 96.3). Podcasts of each show are available on the Sound Cloud at by clicking on the cloud icon.
