Persistent barking can be annoying both for owners and neighbours alike. This veterinary approved collar fits securely around your pet’s neck. Its sound sensitive sensor switches on a pulse of ultrasonic sound whenever your dog barks persistently. This sound is inaudible to humans but irritating to dogs. Your command of “NO” at the same time reinforces your disapproval. Very soon the dog associates the ultrasound and your disapproval with his persistent barking and stops.
Easy programming with 4 high and 4 low settings, the adjustable elastic collar fits any size of dog.
