The number one way that lost dogs are successfully recovered is through the use of flyers and signs that alert the neighborhood and surrounding areas that your dog is missing.
Printing and delivering flyers can be time-consuming and costly. Also, it is illegal for the general public to put flyers into US mailboxes. The USPS has a service to help. How does it work? Use the EDDM® Online Tool to search for neighborhoods you want to reach, and a Postal Service Letter Carrier takes your printed flyers to every home while delivering the day’s mail. Your lost dog flyer gets directly into the hands of the homeowner. EDDM does not require a postage permit.
Go to USPS EDDM® Online or ask your local postmaster for details. Some printing requirements apply.
