Nano mist respiratory humidifier for puppies and small dog breeds. The nozzle releases an even nano mist that keeps airway moisture balanced without drips on bedding. The unit runs quietly enough for nervous animals. The airflow is tuned for smaller breeds to maintain airway moisture at night or in dry heated rooms. Auto shut off cuts mist when water runs out and the spout tilts toward a pet bed or crate. USB power makes it easy to run from a car.
