In the United States, a veterinarian who is practicing veterinary medicine must have at least one license: a State license to practice veterinary medicine (as defined in the state's scope of practice laws), which is only valid for that state.
However, most veterinarians find it extremely helpful to have federal certification and accreditation, so they can administer valid rabies shots and issue health certificates for animals crossing state lines or going international. Also, to handle controlled substances (such as many of the pain medications and anesthetic agents), you must have a DEA license.
