Postal workers are sharing photos of their customers' canines greeting them while they're on the job, and fans can't get enough of the heartwarming pictures.
UPS driver Sean McCarren created the UPS Dogs Facebook page in 2013 as a way to pay tribute to his furry friends that make his work that much more enjoyable. The images have inspired other drivers to post their own pictures, and the page now has more than 1.6 million followers and an accompanying Instagram account.
The posts include the mail carriers' locations as well as some tidbits of information about the dogs. UPS Dogs has also started sharing pictures of other animals met along the way, including deer, sheep, and cats.
Bored Panda has compiled the best photos from the social media pages, proving that even after six years, the dog-lovers still know how to deliver an adorable photo.
