The Maltese is the dog version of a luxury pillow with opinions. Small enough to fit in your tote bag but bold enough to try and boss around your German Shepherd, this pint-sized pooch has been adored by royalty and spoiled by humans for centuries—and they know it. They strut through life with silky white hair flowing in the wind and a confidence level rivaling pop stars.

Don't let their dainty appearance fool you—they have a bark that says, “I will sound the alarm if the UPS man gets too close.” They’re charming, clingy, and will absolutely throw a dramatic stink-eye if you dare leave them alone for more than 15 minutes.

Training them is doable if you use praise, treats, and perhaps a hand-carved throne. Just beware: they may nap in sunbeams all afternoon, but they’ll spring to life the second there’s a crinkly bag or guest to impress. If you want a dog that’s equal parts diva, shadow, and lap-warmer, the Maltese is your star.
