Jennifer Aniston's Dog Norman Dies

"He died a few weeks ago," Aniston's rep confirms to PEOPLE. "He was an old dog and it was just his time."
Over the years, Aniston described her pal as a quiet canine who enjoyed resting at her feet.
"He's my baby boy," she told PEOPLE in February. "Norman goes with me on location – I've got to take Norman."
The actress, who just purchased a $4.95 million apartment in New York, bought the home under the name Norman's Nest Trust.
Earlier this year, the pooch tagged along with Aniston when she was a guest on TV's Chelsea Lately.
Host Chelsea Handler and the crowd went wild for the pup, whom Aniston affectionately called "Norm" and "Normy," and watched as the actress tried to get him to sit, but to no avail.
"He's 15 years old, he doesn't care anymore," Aniston said.
Back when he was a young pup, Norman got into his share of trouble. He reportedly disappeared for two days in 1998 and eventually turned up at an animal shelter. But most likely the event left him unfazed: "Even back [as a puppy] he was as cool as a cucumber," Aniston told PEOPLE in 2008. "He's just a person in a dog suit."
Norman is survived by Aniston's other pup, a white German shepherd named Dolly.
