Isis, Labrador, "Downton Abbey"

Probably the dog with the most famous behind on TV (just watch the "Downton Abbey opening credits each episode!),  Isis is Lord Grantham's (Hugh Bonneville) loyal Labrador. She was once stolen by devious first footman Thomas Barrow, (Rob James-Collier) who planned to hide her and falsely recover the dog to get on Lord Grantham's good graces to become his valet. But when he discovers her missing from where he hid her, his plans are foiled. If only dogs would talk, she'd have quite the stories to tell about the Granthams and especially their hired help.
