Depression Dog is a classic Advice Animal that features the face of a somber, grey-furred dog set against a dark blue radial background. Originating in the late 2000s on sites like Reddit and 4chan, the meme serves as the antithesis to Advice Dog, offering pessimistic or soul-crushing advice instead of optimistic prompts. It gained widespread popularity by tapping into the internet's collective sense of existential dread and social anxiety. Today, it remains a staple for users wanting to express feelings of loneliness, lack of motivation, or the humorous side of being perpetually downcast.
