If you can't spend a minute away from your pampered pooch, you may be pleased to know that there are a number of luxury rentals that allow you to bring your pets along.

Think you're one of the few luxury vacationers traveling with Fido? According to the American Pet Products Association, an astonishing 21 percent of the estimated 45 million pet owners in the United States don't fly, cruise or adventure without their four-legged friends.

"[It used to be] extremely rare to see anyone else on an airplane or at a hotel with their pet," Kelly Carter, former travel writer and pet lover, told USA Today. "Now it's customary to see someone with their pet going through airport security or someone walking their dog through the lobby of a fancy hotel."

From Caribbean villas to rentals in Tuscany, you can let your dog roam around the grounds freely - call ahead to see if your villa provides pet spa treatments or puppy yoga classes so you can share your luxury amenities with your pet.
