Portrait of a German Shepherd dog with a joyful expression, sparkling eyes, and a lolling tongue. The dog's fur is a combination of black and tan with a smooth gradient. The eyes are a captivating amber, drawing attention amidst the fur's rich colors. The painting style should mimic traditional oil painting techniques, with bold, expressive brush strokes that give texture and depth to the animal's fur. The background should be a soft, non-distracting blue that complements the dog's warm tones, providing a calming contrast. The lighting is natural and bright, highlighting the dog's features and enhancing the overall joyful demeanor, ar 1:1 q 2 s 500 v 6
