Say goodbye to receiver collars with the PetSafe Ultrasonic Indoor Bark Control. The PetSafe Ultrasonic Indoor Bark Control will curb your dog’s excessive barking. You can hold the PetSafe Ultrasonic Indoor Bark Control in your palm or position it on a countertop, table or floor. When your dog begins barking extensively, a harmless 2-second ultrasonic tone is activated. Humans can detect it but dogs will and they dislike it. The PetSafe Ultrasonic Indoor Bark Control can be set to activate automatically or it can be set to manual. It will only be triggered by several successive barks, allowing normal “dog talk” to occur. Once your dog will learns the cause of the bothersome sound is his or her barking, the barking will cease. The the Ultrasonic Indoor Bark Control is safe and reliable and quiets within a 25 feet radius of the unit. It requires a 9-volt alkaline battery which is sold separately.
we bought this device to attempt to curb my min pin's excessive barking. she would bark nearly uncontrollably whenever one of us came home or left/returned to a room. i actually had doubts that it would work as advertised. however within ONE use Lily was trained. now when she gets a little out of hand all we have to say is 'box' and she quiets down almost immediately. we don't even keep the battery in the device as we prefer her to be a watchdog when we're at work. AN ABSOLUTE MIRACLE. my only suggestion would be an on/off switch. WOULD UNCONDITIONALLY RECOMMEND THIS TO ANY SMALL DOG OWNERS. JUST A GEM OF A PRODUCT.
