Unfortunately from what you describe it is just hyperactive temperament some dogs inherit from their parents. Sometimes breeders do not care and do not breed for good temperament, sometimes breeder does not match activity level of the family and a dog. I am assuming you are young people so your breeder thought you could handle it. Most times it mellows with age. Sometimes such dogs excel really well in agility but they are major PITA to live with.
Let me also mention a wild guess- when you got your new house, there was a big yard to Culpa to run, so she mellowed out a bit? I am just thinking that for some dogs, walks with human speed as much as exciting is just not enough, you might need to resort to roller bladders, skateboards, bicycle to run her down. Or find a good dog park where she can run at 50 miles/ hr for couple of hrs and then feel tired enough to not be bothered. Some dogs are like that, they need a farm to run and job to have and unless you are training for National agility team they really not dogs for regular homeowner. Obedience while helpful in basics, is too static for such dogs and they benefit much better from agility, flyball, herding.
