When you are planning an elegant evening out you might shop for a small purse just to carry an ID, a small amount of cash and essential cosmetics. For daytime you might choose a large purse that will carry everything under the sun you might possibly need in a day’s time. Dog Clothes you most likely will need room for checkbooks, keys, a wallet, makeup bag, books, coupons, and on and on. Different tasks require different sizes and styles of purses. The same is true with dog carriers.
