Reports of a feud between Pauley Perrette and Mark Harmon on the set of NCIS led to measures being taken to keep them separated during filming. The conflict reportedly stemmed from Harmon frequently bringing his dog to set, which caused discomfort among the cast and crew, particularly after an incident where the dog bit a crew member.
Perrette, known for her advocacy for animal welfare, confronted Harmon about the safety issues arising from the presence of his dog on set. As tensions escalated, steps were taken to ensure they no longer filmed scenes together, with scripts intentionally avoiding their on-screen interaction.
Speculation has circulated that Perrette’s departure from NCIS may be linked to this ongoing discord. Despite the challenges behind the scenes, NCIS maintained its success throughout its twenty-season run.
