I have two the fancy black chanel looking one with chain on the handles and the london tote. Lula is 3 lbs and I have the fancy one in small and the london in Regular?size she fits better in the regular size as she likes to lay down when in a bag. when in the fancy one, she cant lay down "right" and dosnt fall asleep like in the other so she had once barked in the bag. awkward.
.....So, I would not recomed the small as much as you might want it.... but if you do... I was thinking of listing mine on ebay
my 2 complaints about their bags. 1. the clip is on the same side that they can poke their head out of (aka if they jump out its just enough room for them to hang themselves on their collar. 2. the plastic on the fancy one is too "sticky" and makes awkward noises sometimes and can just be awkward to carry.
..butthey are good looking bags... all others seem so tacky in comparison.
