This collar from Clix has been designed to stop unwanted barking, the collar features a microphone which detects barking and automatically emits either a sound or vibration to interrupt the dog's barking. It has been completely redesigned, not only in terms of aesthetics, but the functionality and software have also been improved. The ergonomic shape is comfortable for the dog to wear and the muted grey colour has a more subtle appearance. The material collar is fully adjustable, for a correct and comfortable fit. Small neck size 24-42cm, large 38-74cm.
