We had carpeting all over, except for kitchen and bathrooms. We also took in rescue Dobermans, who wound up almost living in the house with us and the kids. With regular vacuuming, it worked quite well, the kids and dogs could lie around on the floor to watch TV, eat bushels of pop corn and trays of snacks.
Just be sure to get a very good carpet, this will be a long term way of life.
Do some online research, don't just rely on what the salesman tells you.
NEVER rely just on what any salesman tells you!!
