I agree with Tina & Annie

We generally get Medium for their clothes; Marsh is about 10 lbs and Buster is about 16 lbs. Of course they fit differently on each of them, but smalls are too small and they would swim in larges.
If you get boots, go with smalls or x-smalls, depending on the maker, and avoid the cute designer shoes- they fall right off. Most shoes fall off anyways, but the ones that stay on the best are a bit taller with a velcro strap around the ankle.
Make sure you come back here with

of your new wardrobe!
