The Postal Service has issued a special postmark cancellation as a reminder of the organization’s commitment to dog bite prevention.

The cancellation mark features an image of a Labrador retriever with a hashtag promoting the campaign. It replaces the standard six wavy bars cancellation from Oct. 1 through Nov. 1, and it will be applied to mail processed on automated canceling machines.

In 2025, dog attacks on Postal Service employees dropped to a little more than 5,200 incidents nationwide.
