SAN DIEGO â As she typed on a laptop computer on the dining room table last month, wrapping up some work for her job at UC San Diego, Yvonne Grobe could feel the weight of a very serious stare burning into her from the next room. Working in her current office space in San Carlos, Calif., during the COVID-19 pandemic, Grobe slowly turned her head to the left. There, just above a half wall separating the dining area from the family room, the familyâs energetic 3 1/2-year-old dog, Marcus, was up on the back of the couch â his head tilted, tongue out and panting, big brown eyes focused on Grobe, tail wagging furiously.
