Did Pauley Perrette Leave NCIS Because of Mark Harmon's Dog?!?

I'm not sure if I believe this is the reason Pauley left NCIS but it is something to think about, considering that Mark Harmon and she didn't have any scenes together this season.  They didn't even get a goodbye scene really.   So check this out.  The  journalists over at Radar Online may have uncovered the real reason Pauley Perrette left NCIS":  Mark Harmon's dog. Mark rescued a pitbull and named him Dave . . . and he used to bring him to the set.  But in October of 2016, Dave bit a crewmember, causing a gash that needed 16 stitches.   Mark had the dog retrained and stopped bringing him to the set.  But last season he had no dog-sitting options, so he brought him back.  But he kept him in his trailer all day.  Everyone was cool with that . . . except Pauley.   She was furious and started shouting at Mark.  She even told him he never should have adopted a pitbull in the first place.   And she never got over it.  From that point on, she refused to shoot scenes with Mark, and wouldn't sit near him at table reads.  And she ignored him any time he tried to talk to her about it.    A so-called "source" says Pauley didn't feel safe with the dog on the set, even if he was confined.
