Bring peace and quiet to your back garden using the PetSafe® Outdoor Bark Control. Cleverly disguised as a birdhouse, the unit can be placed anywhere in your garden or hung from a tree. Whenever your dog (or your neighbour’s dog) barks, he will hear a safe, but annoying ultrasonic sound that’s inaudible to humans. As soon as he stops barking, the ultrasonic sound stops. The unit can only detect your dog’s bark when he is in front of it, so picking the best placement for your unit is key! This weatherproof unit covers an area of just over 1,000 square metres, but if you need more coverage, simply purchase additional units for your entire back garden area. The battery-operated device uses 1 9-volt battery and lasts up to two months depending on how often your dog barks. With a little time and patience, your dog will learn not to bark in the back garden so that you can enjoy the outdoors together, peacefully. Trust PetSafe® to help to keep your pet healthy, safe and happy.
