What is sus dog meme?

The "suspicious dog" meme features an image of a dog with a skeptical expression on its face, often used to convey a sense of suspicion or disbelief. The image is typically accompanied by humorous captions that play off the dog's expression. The original photo was taken in 2013 by photographer Rafael Mantesso, featuring his bull terrier named Jimmy Choo. The meme became popular on social media platforms like Twitter and Reddit, where it was often used in reaction to news articles, conspiracy theories, and other dubious claims.
