The practice includes referral patients and primary care patients. Limited local field service and community practice units provide primary patient care for a caseload large enough to support teaching programs. Referral patients provide opportunities for referring veterinarians and attending faculty members to share in the investigation and management of naturally-occurring diseases and challenging cases, while students benefit from exposure to a wide variety of learning experiences. After each referral case is completed, clients are instructed to contact their referring veterinarian for follow-up care and treatment of future ailments that might develop. If they wish to return to the Veterinary Teaching Hospital, another referral by their veterinarian is encouraged.
