Animal hospitals in Puerto Rico are licensed by the state veterinary medical board and may also hold accreditation from the American Animal Hospital Association. State regulations govern facility standards, controlled substance handling, and continuing education requirements for all licensed veterinary professionals.

Pet owners in Puerto Rico should identify both a primary care veterinarian and the nearest 24-hour emergency animal hospital before a health crisis arises, as preparation can be critical during after-hours emergencies.

Pet owners in Puerto Rico can verify a veterinary facility's license status through the state veterinary medical board's online directory. Many animal hospitals in Puerto Rico also offer telemedicine consultations for follow-up care and minor health concerns, reducing the need for in-person visits.
