Rumors of tension between Pauley Perrette and Mark Harmon on the NCIS set prompted measures to keep them apart during filming. Allegedly, the conflict arose from Harmon’s habit of bringing his dog to set, causing discomfort among the cast and crew. Matters escalated following an incident where the dog reportedly bit a crew member.
Perrette, renowned for her animal welfare advocacy, confronted Harmon regarding safety concerns arising from his dog’s presence on set. As tensions mounted, measures were implemented to prevent them from filming scenes together, with scripts intentionally sidestepping their on-screen interaction.
Speculation has swirled around whether Perrette’s exit from NCIS might be tied to this ongoing discord. Despite backstage challenges, NCIS sustained its success throughout its twenty-season tenure.
