Training, training, training. Perhaps, training your dog well is the first step to keeping them quiet in a hotel. To be clear, we aren’t suggesting you teach your dog to not bark at all – train it enough to stop barking when asked.  Secondly, do not leave your dog unattended or alone during your stay in the hotel, and it will prompt them to bark at the top of their lungs to find you. If you have to sneak out of the room, do it when deeply asleep or take them with you. Thirdly, make sure that your dog has had plenty of walks for the day so that when you enter the room, he gets tired and falls asleep. Even if he isn’t sleeping, a tired dog usually doesn’t like the idea of barking.  Finally, bring lots of treats or something special, like a puzzle, to keep your dog happy and engaged. A dog with a busy mouth will have less or no time to bark.
