Marnie The Dog, Instagram Star, Dies At Age 18

Marnie the Dog, famous for her long tongue, died "peacefully and painlessly" on Thursday.

The 18-year-old Shih Tzu amassed 1.8 million followers on Instagram after becoming a viral sensation for her adorable expression. Her head was permanently tilted to the left, which was attributed to a case of vestibular disease.

Marnie, who was adopted from a shelter at age 11, became Instagram famous and regularly appeared with celebrities -- including Demi Lovato, Jonah Hill, Betty White, James Franco, Chance the Rapper and Larry King.

She died "peacefully and painlessly" at home on Thursday night, owner Shirley Braha said.

Braha shared the news of the sad passing in an Instagram post on Sunday night.

"Her comfort had been notably declining over the past few days with little hope for improvement and she let me know she had had enough," she said.

"She enjoyed her chicken until the very end."

Braha thanked the 1.8 million followers on Instagram who had shared the "unexpected journey" of Marnie's life.

"All I can feel right now is loss but beneath that I have so much gratitude," she said.

"I’m grateful to the universe for entrusting me with her beautiful soul and providing me with the perfect best friend and companion."

Braha said a public memorial for Marnie will be announced soon -- but that it would be delayed due to coronavirus fears.
