Hey, i've been looking into a purse for meesha, just wondering if they should be bigger so they can move around, or if they should be smaller so they just fit in it?,i want to get on that looks like a purse because alot of places don't allow dogs here so i want her to go unnoticed because she hates being left alone. do i just put blankets down inside of it? also for those who have owened purses whats the best kind? ones you put over your shoulder?,a small bookbag type purse?which is the easiest to use? and the most comfortable one? thanks
