Best Pen pal: how dogs meet american postmen

UPS mail company employee Sean McCarren created a Facebook group five years ago for colleagues to post photos of dogs they meet on duty. And there are quite a few of them. For years, postmen have been delivering letters and packages to the same homes, getting to know the owners and their pets. Postmen have been friends with some of them for a long time, having developed a complex system of greetings. 

According to the postmen themselves, this moment, when their four-legged friends, wagging their tail or loudly meowing, run to them as fast as they can, is the best part of their work. 

Sean McCarren is a UPS mail truck driver.

"Rudy is blind as a bat, but he still follows the sound of my mail truck until I give him a treat."

My new best friend.

And this handsome bulldog is called Jax.

"For a couple of months, delivering mail to the house, I heard two dogs barking inside. Today I finally met them-this is Stella and Zeus."

"This is Buddy. His master says I'm his second favorite person. I always take a break when I meet him, because he won't let go."

Look me in the eye.

Always waiting patiently for me to dig up his treats in the car.

One stop on the route — and half of the package of treats for dogs is gone.

We love cats, too.
