I have a quick question, today i ordered a Pink Puppia Soft Harness for my Scottish Terrier in Medium size, chart below.

M
11~13"
16~19"
7~12 lbs.
Maltese, Beagle, Shih Tzu, Japanese Chin, Beagle, Boston Terrier

I know it says up to 12lbs BUT the Boston and Beagle arent 12lbs full grown? Do you think this will fit my girl? She is 16lbs, yes shes a small Scottie.

Heres link so you can see size chart:
