Whether or not you can leave your dog alone in a hotel depends on the hotel's policy and your dog's behavior. Some hotels may allow it, while others may require that your dog is supervised or crated when left alone. It's important to respect the hotel's rules and ensure that your dog is comfortable and secure when left alone. Consider using a crate or playpen, leaving familiar toys or blankets, and gradually increasing the duration of time your dog is left alone to help them adjust. Additionally, inform the hotel staff that your dog will be left alone and provide your contact information in case of any emergencies.
