He weighs approx. 6 3/4 Lb. and his girth is 11 1/2". The 3 fits him great with one notch to spare so in the winter he can wear it over a sweater. Hope this helps.
Send Maximo his weight, girth etc. and she'll tell you for sure. She was very helpful, even though I didn't purchase one from her, I got one from Canada. |
