Please forgive the color problems with photographs. I had one of those days when everytime I started the photo session, the phone rang, or someone came to the door, and by the time I was actually taking photos, I lost the sun and had to switch to flash.
Digital cameras are nice, but for accurate color, full sun is really needed.
The color most accurate is the upper left, taken in full sun. The next were taken without sun and the rest with flash. Some of the puppies look really sleepy. Nap time came around sunset also, and I had to wake them up to take their pictures. Some days just go like that.
