Dog-walking fundamentals

What do I do if I see someone who walks their dog(s) in our neighborhood without a leash or allows their dog to defecate on someone else’s property without cleaning up after the dog? These acts are against the law and are subject to fines of $250. If you see this occurring, please ask the pet owner to comply with the law, otherwise, the Fairfax County Police ask anyone who witnesses these acts to call 703-691-2131.
