This is often used as a reaction to express intensity, awkwardness, or hyper-fixation. It is frequently paired with sounds like quick sniffing, heavy breathing, or suspenseful background music to emphasize the comedic, weird nature of the dog's expression.
From Unknown, the line "Long nose dog breathing" turned into a universal reaction because the moment hits differently out of context. The combination of delivery, expression, and timing creates something that plain text or an emoji could never replicate. That gap between what you feel and what you can type is exactly where this meme lives.
