A backyard in Walled Lake belongs to the dog first, and to the people who want to sit out in it second. Poop & Scoop Pet Services works that middle ground, keeping yards picked up and cared for so the grass is somewhere you can actually walk barefoot in July. Visits fall into a weekly rhythm through the warm months, when the lawn is growing hard and the yard is in constant use — after a walk down to Mercer Beach, the dog comes home to a clean run of it. Come autumn there are leaves to move and one more tidy before the cold sets in. Small, regular attention is what keeps a yard from ever getting away from anybody.
