These days, it seems like you can't be a true diva unless you've got a pint-size pup peeking out of your purse, particularly a Chihuahua. Songstress Katharine McPhee owns a cutie-pie named Nena, while Demi Moore dotes on Vida Blue, and Paris Hilton has both Tinkerbell and Hendrix.

But before you beat feet to the closest pet store and purchase your own tiny tail-wagger, we recommend perusing the bundles of spastic joy available through Arizona Puppies. Unlike many of the so-called "puppy mills" stationed in malls throughout the Valley, this cooperative of "ethical toy dog breeders" ensures the AKC-certified Chihuahuas they're selling are completely disease free and are bred in a humane manner. Their selection is also quite staggering, offering a variety of different Chihuahua breeds and sizes, including longhairs, shorthairs, deer types, appleheads, and teacups. (A sister site, www.aztoydogs.com, offers such other breeds as Pomeranians, Shih Tzus, and Papillons).

Pricing is a little steep, starting at $500 and going as high as $1,650. But, hey, no one said living the sweet life was gonna be cheap.
