Karing Pet Products is the maker of the K9 Kalmer. The K9 Kalmer is an electronic device used to help reduce unwanted behavior in dogs such as barking and destructive behavior. The Kalmer plays an irresistible, proprietary composition of music, which your dog can can hear but is otherwise inaudible to human. This melody will lure attention away from anxiety producing stimuli and results in a dog's version of tranquility. Our approach to kalming is unlike other products. Our product does not "zap" a dog like many other products on the market or emit a spray. This is truly a humane approach to reducing anxiety and stress in man's best friend.
