Lt. Gov. Aruna Miller is a dog person — so it should be no surprise that she and her family have just welcomed a new puppy into their lives. Poe, an about 4-month-old Australian shepherd, came from Whiteford in Harford County about two weeks ago. She was the last of the litter, Miller said. In the Miller household, Poe joins Hachiko, another Australian shepherd who is about 2 years old, Miller said.
