Dogs and mail carriers. The mail carriers and dogs. It's a complex relationship, isn't it? Maybe even a tale as old as time. Because every single day, the mail carrier dares to invade the dog's sacred area—either zooming by in one of those noisy mail trucks or boldly marching through their territory on foot. From the dog's perspective, it's pure chaos: strange footsteps, the rustle of packages, and—the worst of all, those pesky mail carriers are touching their hooman's stuff!
