That annoyed-looking dog is a popular green-screen meme template known as the “Concerned Dog” or “Annoyed Dog”!
The dog’s expression—where it lays down and slowly raises its head with wide, slightly worried eyes—is widely used to express annoyance, concern, deep contemplation, or the feeling of being judged by an observer.
The original video source for the clip and the dog’s name are not widely documented, but the template itself became hugely popular across TikTok and other platforms for reaction memes
