A close up of a group of dogs standing in a circle

Generate a highly detailed, super-realistic image resembling a group photo of 20 dogs. Each dog should belong to a different breed, arranged with small dogs in the foreground, medium-sized dogs in the middle ground, and large dogs in the background. Ensure that all dogs are fully visible, and none should touch the edges of the image. The composition should be centered, with diffused lighting on a black background. Capture the essence of a diverse and harmonious canine gathering, emphasizing the size gradation and individual breed characteristics.
