I need a stylized shield with a German Shepherd, similar in style to the House Targaryen crest of "House of the Dragon". The background must be black, and the German Shepherd must be light brown. The design must include a detailed, stylized silhouette of the dog, preferably in a dynamic pose. The tail should be long and wavy, accentuated and visible claws, and pointed and energetic ears. Optionally, a motto can be included at the bottom with a medieval style font.
