Tom Thumb, top left, is a serious candidate for the record of smallest dog in the world.
"Owners Susan and Archie Thomson were delighted when he and his brothers and sister were born at the family's West Dunbartonshire home.His siblings are three times the size of the tiny dog, who can fit inside a teacup and cannot reach his mum to feed when she is standing up."I don't want that Tom feels lonely. I found a tiny octopus, a tiny hamster and a tiny frog and he doesn't have to feel sad now. Source for Tom Thumb: mail online.
