How do I know if my dog needs a license?

Dog licenses are mandatory for all dogs three months of age and older. Applications are available at the Delaware County Treasurer’s Office or online, CLICK HERE. 

All dogs must be kept under control and may not be allowed to run at large. Dogs are considered personal property, and owners are responsible for any damages caused by their dogs. For more information, please refer to the Pennsylvania Department of Agriculture, Bureau of Dog Law Enforcement, CLICK HERE.
