Dog Training Collar Attachment - use to control your own dog's barking. This collar attachment comes with batteries and is slightly lighter than the cheaper alternative collar. Attaches to your dog's normal collar. We have been selling this collar for some time and found it to be quite effective. However, technology moves on. You may want to consider the latest bark collar which is cheaper, lighter, smaller, comes complete with batteries and is water resistant CLICK HERE. The dog collar attachment is a battery-operated device that uses high-pitched frequencies to teach your dog not to bark. A sensor detects whenever the dog barks, and the Bark Trainer then emits a series of very high-pitched whistles, which irritate your dog. Reinforce the dog's training with a firm 'No'. * The dog will usually learn to associate barking with the unpleasant noise, which should reduce or even eliminate ‘nuisance’ barking. * Adjust the unit to react only to your dog’s barking. * Simple to use, and harmless to your pet. * No harmful chemicals or pesticides. * Battery-operated (3 x LR44, supplied). * Average battery-life 30-50 days. As with all products involving animal behaviour, results vary from one dog to another,and should be used in conjunction with spoken commands to reinforce the message. Whilst many dogs are trained quickly, some need more patience and perseverence. and in very rare cases the results may be less than totally effective.
