Bring on the Bison!: With Ben Schroeder, Erin Schroeder. It’s a new week and the Schroeders’ vet clinic is bursting with activity. While Dr. Erin has her hands full with a dog injured in a fight, plus a difficult tumor removal, Dr. Ben nurses a newborn calf back to health. Later, the whole family heads to a local Nebraska conservation site to assess the health of a herd bison and watch the breathtaking migration of cranes.
