Producers of NCIS have reflected on Pauley Perrette's departure from the show, giving candid reasons for her exit. Executive producer Charles Floyd Johnson revealed that an incident involving a dog owned by co-star Mark Harmon sparked the process leading to Perrette's departure. Perrette, a passionate animal rights advocate, felt it was unsafe for the dog to be on set. She ultimately decided it wasn't working for her and left the show. Former CBS Entertainment President Glenn Geller praised Perrette for making her character Abby one of the most beloved on television. Perrette has since retired from acting and has openly discussed her strained relationship with Harmon.
