Mark Harmon spotted walking his dog for the first time since leaving NCIS after retiring

Mark Harmon has been spotted for the first time since exiting NCIS after 18 seasons.

The 70-year-old actor was spotted outside his Los Angeles home performing some heavy lifting and household chores, according to DailyMail.com.

The veteran actor and former Sexiest Man Alive was seen only one day after his beloved character Special Agent Leroy Jethro Gibbs made his farewell appearance on the TV show.

The silver-haired father-of-two seems to be keeping active during his acting retirement, as he walked his dogs, brought out trash cans, and wheeled in a huge box delivered to his home.

Mark insisted on taking the package inside by himself, bringing down his own transportation cart and licking his fingers before wheeling it inside.
The actor turned down all offers of assistance from the delivery man.

Mark, who has been married to Mork & Mindy star Pam Dawson for 34 years, was dressed casually in denim pants, a sweater, and suede shoes.

Later that day, he was observed walking his two dogs around the area.

Producer Steve Binder confirmed Mark's departure in a statement earlier this month, but clarified that he will remain an executive producer on the CBS show. 'As an executive producer and dear friend, Mark is a vital part of the show's fabric,' Binder added.

Harmon's final episode on the show saw Gibbs solving a case involving a conglomerate CEO hiring a contract killer to target opponents of a copper mine.

When Leon Vance (Rocky Carroll) handed Gibbs his badge back, Gibbs revealed he was leaving the agency, opting to stay in Alaska, where he'd been for the past few episodes.

In the episode, FBI Agent Parker (Gary Cole) paid a visit to Gibbs' home after he went missing, informing Timothy McGee (Sean Murray),'something tells me he's not coming back.'

There were rumors that Mark was not going to return for the 19th season, though it's believed that he came back because he learned CBS might not renew the show if he didn't return.

NCIS was a spin-off of CBS' JAG, both of which were created by Donald P. Bellisario, which ran for 10 seasons between 1995 and 2005.

The show ended up spawning a number of CBS spin-offs itself, NCIS: Los Angeles, which debuted in 2009 and is currently in its 13th season, NCIS: New Orleans, which was canceled after seven seasons, and NCIS: Hawaii, which debuted this fall.
