Pet+E.R., previously known as the Animal Emergency Center, opened its doors on York Road in 1986 when a group of veterinarians identified a strong need for a pet hospital that was specifically focused on emergency and critical care and that was open beyond normal business hours. These Baltimore-area veterinarians opened the Animal Emergency Center to support patients with emergency and critical care situations when their offices were closed.

As the hospital expanded, it changed its name to Pet+E.R. and, in 2003, moved to its state-of-the-art facility on Luskin’s Hill to better serve the veterinary and pet-owning community in Maryland. In 2016, Pet+E.R. opened its second location in Columbia, Maryland to provide emergency and specialty veterinary care to pet owners in Howard County and the surrounding areas. To date, Pet+E.R.’s hospitals are two of the only critical care facilities in Maryland that are open for patient care 24 hours a day, 7 days a week.


We have brought several pets to Pet+ER, mostly with happy outcomes, but twice for pets who could not be saved. The kindness, patience, consideration, and tenderness with which my animals AND my family have been treated, are exceptional.
