Dale Jolliffe knows all too well that owning a dog means giving up some personal space. But in sharing his home with his Great Dane, Diesel, the Bucks County, Pennsylvania, building contractor grew tired of scooching over every time the pooch wanted to join him on the sofa to watch a little TV. (He wasn't thrilled by the drool the big lug left behind, either.) "Dogs want to be just like you," he says. After hearing similar sentiments from one of his clients, Jolliffe came up with problem-solving furniture that's attractive enough for man and beast alike. Equally appealing, each piece can be built with materials from a home center for well under $100.
