FurDuo 3-Pack Ultrasonic Dog Training Whistles

Train smarter, not louder. The FurDuo 3-Pack Ultrasonic Dog Training Whistles emit a silent frequency that dogs hear clearly but humans barely notice — making them perfect for training at home, in the park, or anywhere you need quiet consistency.

Each whistle is fully adjustable, letting you dial in the exact frequency that gets your dog's attention. Comes with a metal necklace lanyard so you always have one on you during walks or training sessions. Pack of 3 means you can keep one at home, one in the car, and one on you at all times.
