Ohio Rev. Code § 4741.14
The state veterinary medical licensing board may issue, without the examination required pursuant to section 4741.11 of the Revised Code, a temporary permit to practice veterinary medicine to a nonresident veterinarian holding a license which is not revoked, suspended, expired, or under any restrictions and is otherwise in good standing from another state, territory, or the District of Columbia, provided that a veterinarian who holds a current license in this state applies for the temporary permit for the veterinarian. The board shall not require a veterinarian issued a temporary permit under this section to obtain a license under Chapter 4796. of the Revised Code.
A temporary permit issued pursuant to this section only authorizes the permit holder to act as a veterinary consultant or to provide veterinary medical services in this state for a specific animal or animals. When using the services of a veterinary consultant, the responsibility for the care and treatment of the patient remains with the veterinarian who holds a current license in this state and who is providing treatment, or consultation as to treatment, to the patient. The board shall determine by rule the specific purposes for which it may issue a temporary permit and the duration of the permit, not to exceed six months, under rules it adopts pursuant to Chapter 119. of the Revised Code. No more than two temporary permits may be issued pursuant to this section to any one applicant. Any subsequent applications shall be made pursuant to section 4741.12 of the Revised Code.
