mine is 12 pounds. It was way too tight. It would probably fit your 8 1/2 pound but measure around the middle. That is the most critical area. Sure wish it fit Marco.

The manufacturers all have different measurements. But I have 4 dogs 1 small, 1 med, 1 lrg, and 1 Exlrg, I actually took the time and measured them all and this page was the closest I found. Hope this helps.
thanks, that was so nice of you. I used to have a pet boutique and they all run so differently. They were going to go for a standard, but don't know if they ever did. This is for a small under 10 pounds. Mine is 12 pounds and it is way too small for him.
