21 U.S.C. § 822(e)(2) Persons required to register—Separate registration (Controlled substances)
Veterinarians do not need a separate registration to transport and dispense controlled substances at a site other than their registered place of business as part of their usual course of veterinary practice. However, the site of transporting and dispensing must be "located in a state where the veterinarian is licensed to practice veterinary medicine and is not a principal place of business or professional practice."

Selected cases

Fitzgerald v. Board of Registration in Veterinary Medicine, 399 Mass. 901 (1987)
In a case concerning a veterinarian's alleged improper treatment of an injured dog, "the hearing officer, in construing and applying the terms 'malpractice,' 'gross misconduct,' and 'conduct reflecting unfavorably on the profession of veterinary medicine,' as those terms are used in G. L. c. 112, Sections 59 and 61, correctly looked to the general standards of ethics and practice which are adhered to in the profession of veterinary medicine."

Kippenberger v. Board of Registration in Veterinary Medicine, 448 Mass. 1035 (2007) 
"Substantial evidence supports the board's decision that Kippenberger's treatment of each of the dogs failed to meet the acceptable standard of veterinary care. Kippenberger's treatment ranged from performing unnecessary surgery to misdiagnoses to neglect. Kippenberger's assertions in his defense are either unsupported by the record or insubstantial. Even if, for example, the board incorrectly stated that Kippenberger had failed to offer any defense of his care for one of the dogs, substantial evidence still supports the final assessment that Kippenberger's care of that dog was substandard."

Roman v. Board of Registration in Veterinary Medicine, 495 Mass. 1044 (2025)
"Contrary to Roman's argument, the board did not abuse its discretion by considering her prior disciplinary history in aggravation merely because her prior misconduct was different in kind from that at issue here. In the circumstances of this case, the board properly found that Roman's history evidenced a pattern of failing to comply with the requirements of her profession. The board did not abuse its considerable discretion by suspending Roman's license for two years."
