Have you ever wondered why your dog acts like it's the best day

(0:00) Have you ever wondered why your dog acts like it's the best day of his life every single time you (0:05) walk through the door? Psychology says dogs don't understand time the way humans do. To them, every (0:11) moment you're gone feels like forever. When you leave, his brain releases cortisol, the stress (0:17) hormone. He feels uncertainty, like a child lost in a crowd. But the second he hears your footsteps, (0:24) something incredible happens. His brain floods with oxytocin and dopamine, the same chemicals (0:31) humans feel when they hug someone they love. That's why he runs, jumps, spins, and can't (0:36) stop wagging his tail. It's not just happiness. It's relief. It's love and motion. Because in his (0:44) mind, you didn't just come home. You came back. And to him, that means everything. So next time (0:51) he greets you like that, don't brush it off. Get down, look him in the eyes, and remind him (0:56) you're always coming back.
