Answer:
In Montgomery County, Maryland, a dog is considered to be illegally "at large" if it is outside the owner's premises and not leashed, unless it is a service dog, is in a dog exercise area designated by the Maryland National Capital park and Planning Commission, or is participating in an approved activity.
Any other animal (i.e., cat or livestock animal) is at large if it is outside the owner's premises and not leashed or immediately responsive to verbal or non-verbal direction.
The common area of a homeowner's association, condominium or cooperative is not the owner's premises.
Penalty for Violation: $100 for first offense, $500 for each subsequent violation.
