Pacing before the procedure

Ellie, a four-year-old Labrador Retriever, paces in a kennel on Friday at the Columbia Pet Hospital between procedures. The first procedure involved removing fat cells, which will then be used to harvest stem cells. The second procedure occurs about an hour after the first, and involves injecting the stem cells into affected areas — in this case, Ellie’s shoulders and elbows.
