I purchased the red in a medium color for my 14lb Shorkie, his long but slim. Fit is okay.
I also purchased the blue in large for my shih tzu/maltese mix that has a wider chest and is chunky at his old age. I am glad it fits his chest and belly. I also am happy that it's easy to place on my 14 year old dog and not hurting his legs due to flexibility.
FYI: neck area is pretty loose on both dogs. Only had it on for a few hours.
