Diamond dogs living it up

Some of us toss Fido some scraps off the dinner plate and call it a night. But for those channeling Leona Helmsley, the hotel magnate who left $12 million to her Maltese, Trouble, there's no shortage of over-the-top products to pamper a pet. At Three Dog Bakery in Santa Monica, owners Rocky and Hannah Keever are experts. Customers routinely ask to see the priciest pet paraphernalia, without even looking around the store. For the pooch who has nearly everything:

Does your canine want to put on the dog? Designer Cuddly Ruff offers a necklace set of cultured pearls and a diamond pendant. $2,325

If your teacup terrier is decked out in diamonds, surely you can't expect her to walk. Tote her around in a Creature Couture carrier bag, which comes with vents and fold-down flaps in case Princesswants to take a look around. $269.95

Too hot for a walk? Bring the fire hydrant indoors, grass and all. These Pet-a-Potty mini-lawns come with a drip tray that can be emptied. Choose fake or real grass and a size that suits you and your best friend. $199 to $2,200

Want to take Rover camping but can't bear to have him rough it in a pup tent? Vancouver, Canada-based Straight Line Designs Inc. makes a mini-Airstream trailer. This ultra-sleek doghouse is handcrafted and comes with hardwood floors. $5,000

Even dogs like to "pawty," or so say the Keevers, who play host to monthly happy hours at their shop. Three Dog Bakery's catering packages (Bark Mitzvah, anyone?) include gift bags for tail-wagging guests, pupcakes, a bone-shaped cake, party hats and a bottle of Sauvignon Bark gravy for a party of 10. $249.95
