Puppia now makes harnesses in a size X-small. I know a while back there were several people on here interested in that size and the smallest that puppia made at that time was a small which fits a 12-16 inch chest. But now they have a size 9-12 inch chest in the solid color puppia soft harnesses. There are also new colors/patterns available but those are only available in size small and I have those available on my website.
