"Create a hyper-realistic image of a blond man with a beard, moustache, and blue eyes, walking a dog on the beach. The dog should be a mix of American Bully and Chow-Chow, with a coat in shades of brown and light brown. The setting should feature a sandy beach with gentle waves in the background. Capture the details of the man's attire and the textures of the dog's fur, along with the dynamic and relaxed interaction between the man and his pet."
