Dolphins help save tired dog stuck in canal

MARCO ISLAND: Feb 23, 2011 Some persistent dolphins are being credited with saving a dog that had run away on Marco Island. The dog's owner said he had been missing for 15 hours before the dolphins alerted neighbors.

Cindy Burnett lives off South Bahama Avenue on Marco Island.

She says her 11-year-old Doberman named Turbo disappeared late Sunday night after his gate was left open.

And that's when Burnett and her sons went looking for him.

"I searched and searched and called his name. I drove through this street at least five or six times," she said.

Late Monday morning, Turbo was finally found.

"He was shivering and a lot of distress," Burnett said.

She says Turbo could have been in the canal water for 15 hours. And she says it would have been longer if it weren't for a persistent splashing coming from the water. {continued}
