The kennel just won't cut it: Gone are the days of excluding four-legged friends from family vacations. As more and more travelers are checking in with Fido and Fluffy in tow, hotels have had to accommodate a new breed of guests. With the demands of pet-loving travelers ringing in their ears, hotels have stocked up on everything from treats to toys. But while some properties are content with simply letting pets on the premises (for a fee, of course), other hotels roll out the welcome mat. The following hotel brands have proven themselves among jet-setting pets and the humans who love them. Luxury and lavishness may not be part of Red Roof Inns' mantra, but for most pooches, pampering makes for an unexpected perk. This national chain is extremely popular among the road-tripping set, with more than 345 locations offering simple, dependable accommodations. For less-picky pets, the Red Roof Inn will do just fine. Although the hotel chain doesn't offer any special amenities, you can rejoice in knowing that you won't have to pay extra for your furry friends.Pet Policy: Due to some state laws and ordinances, not all Red Roof Inns can accept pets, but service animals are always welcome. Guests are limited to one pet per room, and animals must be declared during registration. The Red Roof Inn prohibits guests from leaving pets alone in guestrooms; outside of the rooms, pets must be on a leash or in a carrier at all times.Pets can always stay at the Westin, and thanks to the numerous amenities provided, your beloved family members will be happy you chose this chain. Upon arrival, dogs and cats are greeted with a welcome kit filled with treats and information on nearby pet parks. And while you're kicking back in your Westin Heavenly Bed, your four-legged friends will be living the high life with their custom pet beds and food bowls.Pet Policy: All of Westin's 142 North American properties are happy to accommodate animals weighing up to 40 pounds, although general managers may be inclined to let larger pets stay as well. Some, but not all, Westin hotels may charge an extra fee for accommodating your dog or cat, and you will have to sign a waiver should your pet cause any damage. Make sure to check the pet policy at specific hotels to see if there are any other preparations you'll need to make.Size doesn't matter as much at Sheraton Hotels and Resorts: This chain will accommodate animals up to 80 pounds and sometimes more, depending on the branch. That's 40 pounds more than its Starwood sibling, Westin. Plus, Sheraton's canine and feline clients receive their own beds and dishes, not to mention ample treats. Meanwhile, you'll have no trouble acquiring info on nearby pet-friendly attractions from the concierge.Pet Policy: There are 222 Sheraton hotels in North America, and each one is happy to host you and your pet. However, since policies may vary slightly from property to property, it's best to check ahead. While some hotels charge an extra pet fee, all Sheraton properties ask you to sign a waiver should Fido decide to go all Rolling Stones on the hotel room. You are free to leave your pets alone in the room, but they'll need to be on a leash in the halls.The motto here is P.A.W.—Pets Always Welcome. Like their human companions, dogs and cats will be treated like royalty at Fairmont hotels. Your pals with paws will be welcomed with custom beds, bowls, and treats, and you'll have easy access to information on nearby dog parks and pet-friendly places. Some (but not all) Fairmont properties also offer on-site animal services: The Fairmont Miramar Hotel & Bungalows in Santa Monica, Calif., for example, will take good care of your pup with walking and pet-sitting services as well as spa treatments.Pet Policy: Not all Fairmont hotels are pet-friendly; those that are usually charge a pet fee of $25 per night to cover the cost of any damage. Although the average weight limit is 25 pounds, some Fairmont managers allow larger animals to check-in. Your pet must be up-to-date on his or her vaccines to stay at a Fairmont property.One thing's for sure: "Loews Loves Pets." In terms of amenities, special beds are just the tip of the hospitality iceberg. Upon checking in to a Loews hotel, your pet will be showered with treats and toys, not to mention a few necessary items like bowls, litter boxes, pooper scoopers, and even leashes and collars. And that's not all: On top of pet-sitting services and special room-service menus, some Loews properties also invite visiting dogs to participate in special programs. The Loews Coronado Bay Hotel in San Diego hosts a surf-dog competition every year, while the Loews Don CeSar Hotel in St. Pete Beach, Fla., boasts an in-house doggy masseuse. With perks like that, your animal will really feel like a VIP ("Very Important Pet").Pet Policy: Loews enforces a limit of two pets per room, and all four-legged guests must be up-to-date on their vaccinations. Upon checking in, you will have to sign a waiver and pay a one-time cleaning service fee of $25. You are not allowed to leave your pets unattended at any time, and animals are not allowed in restaurants, fitness centers, or on pool decks.Like its Starwood counterparts, W hotels are extremely pet-friendly. In fact, your canine companions and feline friends will be more spoiled during a W stay than at most other Starwood brands. As part of the P.A.W. (Pets Are Welcome) program, the chain's 31 North American properties greet four-legged guests with an arrival kit including treats, toys, clean-up bags, and even ID tags. Pets will also receive a special bed, bowls, floor mats, and turndown treats. However, animal lovers should expect to shell out a pretty penny for pampering their pooch. A $25 per-night pet fee and a nonrefundable $100 cleaning fee will be added to the bill.Pet Policy: Most W hotels welcome pets up to 40 pounds, and only one animal is allowed per room. Upon check-in, you will receive a pet-in-room sign for your door, which must be displayed. Always keep your pal on a leash or in a carrier when outside the room (animals are not allowed in restaurants or bar areas), and you will have to be present when a hotel staff member is in your room with your pet. If you are leaving your dog or cat alone in the room, you must notify a staff member.There's no doubt about it: Kimpton adores pets.
