Ever notice how watching dog videos online instantly lifts your mood? Turns out, there’s a weird twist: if you just saw pics of happy pups, you might actually think the dogs in the next video look sadder—and vice versa! Psychologists call it a “contrast effect,” and it only happens with dog images, not people or landscapes. So, next time you scroll through adorable or sad dog pics, your brain might be playing tricks on how you see your own furry friend! #Pets #DogScience #PetOwners
