The Animal Welfare Regulations define an attending veterinarian as a person who has:
*If the attending veterinarian does not have training or experience with every species at the facility, they are encouraged to consult with another veterinarian who has experience with these species. Individuals with expertise on a given species, such as behaviorists or personnel at facilities with a good track record for USDA compliance and animal welfare, may also be consulted.
The facility may choose to employ an additional veterinarian with expertise in this species as well.
The Animal Welfare Regulations do not require state licensure or accreditation for attending veterinarians. However, state licensure is required to issue health certificates and is required in most states to administer rabies vaccinations. Accreditation may also be required for issuing health certificates for interstate or international transport.
In cases where the attending veterinarian is not licensed, a facility can use a consulting veterinarian who is licensed to provide services regulated by that state under the oversight of the attending veterinarian.
