Emergency & Critical Care

At Cornell University Veterinary Specialists, our doors are always open. We are proud to offer world-class Emergency and Critical Care 24 hours a day, 7 days a week, 365 days a year. We understand that pet emergencies are stressful and upsetting; our experienced team is here to help with knowledge and compassion.

One of the most dramatic changes in veterinary medicine in the past 15 years has been the tremendous advancement in the field of Emergency and Critical Care (ECC). With the development of ECC as a specialty, we have profoundly advanced our ability to manage emergent, critical, and complex cases. With this ability has come the realization that, properly managed, many pets survive conditions that were previously considered fatal.

  • Specialist coverage 7 days per week. Board-certified ECC specialists are in the hospital every day, managing emergency and ICU patients and consulting on cases internally and externally.
