A bug-eyed Chinese crested hairless pooch who was officially crowned the World's Ugliest Dog has died at age 17.

The lovable Miss Ellie, whose lopsided tongue always stuck out of the side of her mouth, died on Tuesday in her Tennessee home, the local Mountain Press daily newspaper said.

Rescued by owner Dawn Goehring when she was seven years old, Miss Ellie, who drew smiles with the shock of blonde hair above her eyes, had helped raise more than $US100,000 for the Humane Society of the Tennessee Valley.

Despite being blind in her final years, she won Animal Planet's World's Ugliest Dog award last year.

She was also featured in numerous commercials and television programs.

Miss Ellie had been set to travel to California this month to defend her title.

She was part of a troupe of dogs that Ms Goehring trained and which performed regularly at the Comedy Barn in Pigeon Forge.

Ms Goehring says she is now planning on raising money to open a new animal shelter.

"I am going to make that my driven goal to do in her honour," she told the Mountain Press.
