Create a simple 2D cartoon of a pack of dogs of different breeds sitting in front of the camera. Each dog should have a unique, friendly expression, showcasing their distinct characteristics. Include a variety of breeds such as a Labrador Retriever, Poodle, German Shepherd, Bulldog, Beagle, and Dachshund. Arrange them in a playful and relaxed manner, with some dogs sitting, some with tongues out, and others with wagging tails. The background can be a plain, light-colored setting to keep the focus on the dogs, creating a charming and heartwarming scene.
