In 2007, the Boston Globe reported that Romney strapped the family dogs crate to the roof of his station wagon during a 12-hour road trip from Ontario to Boston — with the dog Seamus inside. Romney had to stop during the trip and wash down the car after the dog began suffering from diarrhea.

Sixty-eight percent of voters surveyed said Romney treated the animal “inhumanely,” including 63 percent of Republicans surveyed.
