Holland — As soon as she enters the double glass doors, her leash tightens and low pitched “woofs” fill the air.
Her nails make a clicking sound as she zig-zags down the long corridor of Holland Hospital, picking up speed.
A couple sitting on a bench gives in to her curiosity and pleas for attention and reach out their hands to pet her as she passes by.
Then it’s on to the hospital gift shop to get her dog treat.
Soon enough she’s on the elevator, awkwardly rotating her 115-pound body so she’s standing facing the door — always the first to exit and greet the patients.
It’s just another day on the job for Sierra, a 7 1⁄2-year-old Alaskan Malamute therapy dog.
