The bow wow WOW boutique aims to please the pickiest of pooches.

Paris has probably never shopped for Tinkerbell in PETCO, and there's no reason why your dog shouldn't have the best either. Since 2002, Maxwell Dog has been helping customers pamper their adorable pups. Pet caretakers—"owners" is so derogatory—can find a mountain of mutt mattresses in chic, groovy patterns; outfits from preppy stripes to sparkling glam-rock Hello Kitty; and leashes and collars in every style from Italian leather for the power pooch to bejeweled for the prissy pup to skull-and-crossbones for the punk puppy. Dog lovers can also ensure their precious darlings eat in style. The store carries a variety of dog bowls like the minimalist plastic model (à la Philippe Starck) or a posh Burberry-inspired plaid. And if youre just looking for a sweet treat to reward your dog, gourmet delicacies like doughnuts, cupcakes and bacon croissants will get your pooch drooling.—Elisa Jacobs
