Night Park Portrait of Two Dogs

Create a photorealistic square close-up portrait of two friendly dogs sitting cheek-to-cheek in a dark park at night: on the left, a {argument name="left dog breed" default="black Labrador retriever"} with glossy black fur, warm brown eyes, floppy ears, an open smiling mouth with pink tongue visible, and a bright {argument name="collar color" default="red"} collar with a small metal ring; on the right, a {argument name="right dog breed" default="German shepherd"} with tan-and-black fur, upright pointed ears, brown eyes, a slightly tilted head, and an open happy mouth with tongue out. Both dogs face the camera directly, their muzzles touching affectionately, filling most of the frame from chest to ears. Use realistic flash photography with crisp fur detail, wet nose highlights, catchlights in the eyes, and shallow depth of field. The background should be an out-of-focus nighttime urban park with dark grass and warm golden circular bokeh lights from distant streetlamps and buildings. Composition is intimate, centered, symmetrical but natural, with the Labrador occupying the left half and the German shepherd the right half. No text, no humans, no extra animals, no watermark.
