It was a scary story out of Iowa when the wires reported that Mike Huckabee's son and some friends were in a car wreck while returning home to Arkansas after the caucus the Republican presidential hopeful won. But what went unreported was what happened to Huck's three dogs, who had traveled on his campaign bus in Iowa. Well, we've got word that they are OK, too. The littlest, Toby, a Cavalier King Charles Spaniel, was thrown from his kennel and wandered off after the wreck, but somebody picked him up. Two others, Huck's hunting Lab, Jet, and his wife's Shih Tzu, Sonic, were tossed around but not hurt badly. Yes, Sonic is named for the hamburger joint. Says Huckabee of his dogs, now heading to South Caro-lina to campaign: "They really keep Janet and me mellowed out. It was killing us not to have them with us" in New Hampshire.
