San Francisco Sheriff's Department took to Twitter and posted a photo of two deputies with LiLou after visiting patients at Zuckerberg San Francisco General Hospital.
Lilou loves to do good and is often seen wearing a tutu flowered wreath and painted hoof nails.
Last year, she became the latest member of the "wag brigade" at the San Francisco International Airport.
Her job is to make people feel happy and more relaxed.
Lilou's handlers say when people see her, they pet her, take selfies and hopefully forget they're waiting at an airport.
