This Halloween, dress your pup up as one of your favorite Starbucks drinks. This costume is easy to DIY if you have a small enough dog to slip an actual Starbucks cup over. Or you can make a cup by wrapping cardboard around your dog and drawing on the logo. If you're feeling extra adventurous, you can even dress your dog as a barista for the Oct. 31 festivities. With as extensive a brand as Starbucks, the options are practically limitless.
