Extended Equine Certificates of Veterinary Inspection (EECVI) Available to California Veterinarians:

As a reminder, starting January 1, 2020, California veterinarians can now issue Extended Equine Certificates of Veterinary Inspection (EECVIs) for equines using GlobalVetLINK (GVL). This electronic movement document requires a current Equine Infectious Anemia test and is valid for up to six (6) months. This EECVI may be a favorable option for horses or other equines that frequently travel interstate, such as for shows or ranch work. Owners are required to log every trip movement to obtain a travel permit and must verify the health of the horses prior to travel. To utilize this service and create an EECVI, veterinarians must be signed up with GVL. To learn more about EECVIs and see which other states are participating in the program, visit https://www.globalvetlink.com/eecvi/.
