Mailmen are courageous and unstoppable. Nothing stops them from being able to deliver letters and packages to the masses. Not even the neighborhood dogs, no matter how hard they try.
Like cats and squirrels, mailmen are often portrayed in fiction as a dog's favorite target. Mostly it's harmless encounters like barking or chasing them away. Other times, because Predators Are Mean, the Angry Guard Dog outright attacks the letter carrier. Sometimes the mailman gets his revenge or the dog gets his comeuppance, especially if the mailman has a dog of his own to counter back.
Sometimes instead of the mailman, the target is a paperboy. In older media, one may see a milkman or a telegraph deliver as the target of the dog's wrath.
Played for Laughs if the mailman is intimidated by a comically small dog like a chihuahua. (Though if it's a particularly poorly trained and aggressive small dog, this might be a Justified Trope.)
- One Nike shoe commercial follows the Point of View of a dog on a leash, taking a brisk walk with its owner. The dog at one point encounters a mailwoman and makes a point of growling at her, eliciting an "Eek!" The dog chortles and remarks, "I love doing that."
- There was a series of commercials for something which had people announcing that they were leaving the job they currently had and were joining the NBA.

The other player barks at him and makes him drop the ball.

- A comic book story based on Krypto the Superdog features an intergalactic mailman who's constantly being attacked by dogs everywhere he goes. The Dog Stars (even Brainy Barker) can't help but bark at him in spite of knowing he's a harmless character who doesn't deserve this kind of treatment.
- Garfield enjoys harassing the local mailman, he even lampshades the trope by asking, "Why should dogs have all the fun?" Sometimes he just pulls harmless pranks while other times he will violently attack him or catch him in an elaborate booby trap. The mailman occasionally gets his revenge on Garfield.
- In an Easy Amnesia sequence, the one thing Garfield remembers by himself is that he used to terrorize the mailman. He even implies that this must mean it's the most essential part of his nature - More so than his overeating!

- Pooch Café elevates this to an almost-religion amongst its dogs, to the point where one plotline has the doggie denizens distressed to discover that their resident mailman foe has a dog — which they try to "rescue" and free from what they assume must be some kind of brainwashing. Another plotline has main character Poncho go against the code and try to rescue a mailman who has fallen unconscious in the snow by dragging him onto a train car. They are found by hobo dogs, who screech that Poncho has brought "the enemy" into their midst; Poncho bluffs that instead of helping the mailman, he had captured the mailman — and consequently is made king of the hobo dogs.
- Averted by Daisy, the Bumsteads' dog in Dean Young's Blondie, who bears the mailman no ill will and is harmless. It's Dagwood, zooming out the door in a blind panic, that's the mailman's chief hazard.
- Used several times in The Far Side:
I sensed the mailman's fear as he opened the gate. It was like a warm stench in the air — so thick you could cut it with a knife. Suddenly, I felt myself growing dizzy — as if the fear was a powerful drug. The entire yard began reeling. And then I heard his soft, plump calves begin calling to me: "Zeeeeeeeeek...Zeeeeeeeek...bite us, Zeeeeek...biiiiiiiite uuuusss..."
- In one panel, a mailman comes through a door with seven dogs hanging off him. He says to his wife, "Gimme a hand here, Edna... I got into a nest of weiner dogs over on Sixth and Maple."

- Referenced in Up when Muntz's dogs see Russell in his scout uniform and assume he's some kind of small mailman (because apparently anyone in an uniform is a mailman to a dog).

- Teen Power Inc.: Zigzagged in "The Bad Dog Mystery." Jock (the eponymous dog) got along great with the previous mailman (who'd throw letters for him to catch) but constantly chases the new mailman, because the new mailman is a burglar who hurt Jock's owner.

- Newman has a great disdain for dogs as a mailman as shown in "The Engagement" episode.
