You can technically leave your dog in your tent for a short amount of time, but it’s not recommended to do it for extended amounts of time. While it would be considered safe to keep your dog in your tent while you go fetch something from the car or go on a short walk, it’s best if this is kept to a minimum. Dog’s don’t like to be left in tents alone, especially if it’s during the hottest part of the day, or if there’s a big thunderstorm. They will be left feeling scared and might try to claw their way out of the tent. This will leave them with unnecessary stress and anxiety that could otherwise be avoided. If you think you’ll need to leave your dog inside of the tent at any point on your trip, then it’s a better idea to not bring your dog with you at all.
