Search the web for pet-friendly hotels, vacation rentals, campgrounds, or bed & breakfasts. Travel sites like Expedia and Priceline let you search pet-friendly. It will usually say on a hotel's website if it is pet-friendly, but you can always give them a call if it's not clear. Some hotels, like Kimpton, even provide pets with their own bed, snacks and water bowl. Most places do require a pet fee though, so be prepared.
It doesn't need to be said that dogs love the outdoors. Think endless fetch, swimming in the lake, and room to run and play. Before going to a state park, check to make sure it is pet-friendly.
Soak up the sun while your dog plays! Another often dog-friendly option is to take a beach vacation. Research dog-friendly beaches beforehand. Never leave your dog unattended. Off leash options.
Vineyards that allow dogs.
Your dog should have at least two forms of ID, such as a collar and tags, a tattoo or a microchip. ID tags with your address and phone number should be attached to a buckled collar. Ideally, an ID tag should also have your vacation destination and a number where you can be reached.
Food, Water, and Equipment
Pack a supply of your dog's regular diet. Bring food bowls, water bowls, grooming equipment, a sturdy leash, and waste pickup materials like plastic bags. Familiar blankets, pillows, toys, and treats will make a dog more comfortable in a strange environment. Tip: In the case that your dog has an accident, white vinegar works as well as any commercial product to remove "doggy smells" from carpeting and upholstery.
Medications and First-Aid Kit
If your dog isn't already on heartworm medication, check with your vet to see whether she will need it for the region you are visiting. Bring any medications your dog normally takes, and consult with your vet about car- or airsickness and the need for tranquilizers. Pack a canine first-aid kit (available at pet-supply stores) to deal with minor emergencies.
Take rabies and health certificates with you—they are required for crossing international borders and at many campgrounds and parks. Take your vet's phone number as well.
