As of June 29, MSU's Small Animal Emergency and Critical Care Medicine (ECCM) operations have modified:

All walk-in patients will be evaluated. Life-threatening cases will be admitted. Cases evaluated as stable will be referred to the client’s primary care veterinarian, other facilities, or other services within the MSU Hospital, if possible. Monday–Friday, from 8:00 a.m.–1:00 p.m., the ECCM Service will operate as a “referral only” service. However, walk-in patients with critical illness or immediately life-threatening problems will always receive care. Referring veterinarians should call 517-353-5420 prior to sending any patients to MSU. View the Hospital's full web page.
