The COA No-Bark Collar is a cost effective method designed to stop unwanted barking, and it is safe and humane (unlike shock collars).
	
It works best when combined with positive reinforcement training, and to maximise effectiveness, should not be left switched on for long periods of time.
	
The ergonomic, light-weight shape is more comfortable for the dog to wear and the muted grey colour, has a more subtle appearance.
	
The collar features the option to use either sound or vibration and has either two or three level settings dependent on the size of collar. Barking triggers either a high pitched sound or a vibration to interrupt the dog's barking. This interruption provides opportunity to 'click and reward' dog to effectively support the quiet behaviour.
	
The material collar is fully adjustable for a correct and comfortable fit.
