Harford Emergency & Referral Veterinary Services was founded in 1988 as Harford County's first 24-hour emergency and critical care animal hospital. Our history since then has been one of dedicated service to the pets of Bel Air and Harford County and to their owners. HERVS is open 24 hours a day, and no appointment is required. Whether you're facing an emergency outside your veterinarian's customary business hours or your veterinarian has referred your pet to us for surgery or intensive care, you'll benefit from a modern, fully equipped facility and a highly trained staff.
