The Pink Dog meme, officially known as Lovehound, originated as a set of animated stickers for Telegram created by the artist Sveid. Featuring a small, vibrantly pink canine with exaggerated expressions of love, the character quickly transcended the messaging app to become a staple of 'stan' culture and reaction images on Twitter and Discord. The meme typically depicts the dog with heart-shaped eyes, vibrating with excitement, or clutching a heart, making it the universal internet symbol for being 'down bad' or overwhelmed by affection. Its popularity lies in its ability to perfectly capture the high-energy, chaotic nature of modern online infatuation and adorable obsession.
