Those shrill ear-piercing barks will be a thing of the past with the PATPET U01 Ultrasonic Pet Behavior Training Remote. It’s a safer, effective method that you can add into the training process with an ultrasonic sound that can only be heard by your dog—he’ll stop the mischief without a hitch. The handy remote even works up to 30-feet, so it’s perfect for outdoor use! Different from the traditional e-collar, it adopts a more humane and gentle way to correct bad habits because it does not have a shock stimulus function. If your furry friend is just in the early stages of bad behavior, you can use this product for behavioral training. It can also be used on other pets including horses, rabbits, cats and more!
