Design a retro-inspired typography graphic with the phrase 'Just a Mom Who Loves German Shepherds' in a groovy, 70s-style font. Incorporate a stylized, semi-realistic German Shepherd illustration, possibly wearing sunglasses or a bandana. Use a vintage color palette of mustard yellow, burnt orange, and teal. Add a distressed texture to enhance the nostalgic vibe. Ensure the design is isolated on a black background.
