Cute dog (like you didn't know) Very nice color. I particularly like the the catchlights in the eye and the texture in the nose... these things give it a real, living quality.
to me this subject almost blends into the bg not stand out from it - a different colour would have been much more effective - a high key shot would have made puppy really pop
I think this would have met the challenge better if the blanket was a different color as it is too close to the color of the dog. As a pet portrait, I find myself looking more at the blanket since it is so bright, and miss out on the cute dog.
Nick, I love her expression -- and am glad you are showing Ruby off with a larger image this time. ;)
In this image she seems a bit too red, but I can't tell if it's from bounced lighting off the read cloth or from over-saturation of the red channel. This blends her into the background a bit (although not heavily) which causes her to not be offset as much as she could have been. It's not a big issue, so I hope the voters don't penalize for it.
