Pauley Perrette reportedly left 'NCIS' because of an incident involving Mark Harmon's dog

After actress Pauley Perrette announced last year that she would be leaving NCIS after 15 seasons, fans were left confused as to w.

While fans were sad to see Pauley go, the actress assured everyone that all was well between her and the network, CBS, and that she was leaving of her own accord. But Pauley's recent comments on social media seem to suggest there might be more to the story.

In October 2016, Harmon’s rescue dog Dave bit a crewmember on the set of the CBS drama, leaving the victim with an open wound that took 16 stitches to close. But last season, the actor was forced to bring the dog to work because he had no one to watch him.

According to Vanity Fair, the reports from multiple individuals familiar with the situation allege that Mark's dog bit someone on set, and Pauley apparently did not approve of the animal being allowed to return.

This disagreement supposedly sparked a feud between Pauley and Mark, who plays Agent Leroy Jethro Gibbs and serves as executive producer.

As it turns out, that does seem to be the root of the problem, and that was what Pauley was referencing in her tweets, according to sources.

Apparently, in the past two years, Mark Harmon and Pauley couldn’t even film in the same room, that’s how bad the drama was between them.

The situation escalated dramatically, creating discord between two key players on the set of one of CBS’ most bankable hits. As astute viewers had already noticed, the characters had started appeared in fewer scenes together in recent seasons.

Perrette felt that after the incident, someone else might get hurt by the dog and shared her concerned with the show bosses, but they sided with Harmon because he is a producer on the show. So she decided to leave the show.

Perrette, who played Abby Sciutto on 352 episodes over 15 years on the police procedural, was grateful for her former network’s support. “I want to thank my studio and network CBS They have always been so good to me and always had my back,” she tweeted.
