Man's best friend? More like full-fledged family. And, for many, a home isn't truly a home without a furry fido to share it with. In honor of the (admittedly faux) holiday, National Dog Day, we wanted to share some of our favorite person-pet portraits from our house tours. They're a heartwarming glimpse into these special relationships and will both make you smile and want to cuddle up with your own canine (or borrow a friend's).
