Be sure your dog is clean and flea-free before your trip. At rest stops and gas stations, be sure to attach your dog's leash to his collar before opening the door. It could be very difficult to locate a lost animal in unfamiliar territory. Don't leave your pet for more than a minute or two in the car. When visiting the beach in summer, keep your pet's comfort in mind.
Sand can get extremely hot and blister paws.
A beach umbrella is a must, especially for dark-colored dogs. And don't forget fresh water for drinking. If you do a lot of hiking or are staying at a heavily wooded resort or campground, check for ticks daily. If you have a large dog, pack just enough to get you to your destination, then purchase more once you've arrived. The last thing you want on your trip is a dog with an upset stomach.
