Checkout: http://barkcollarreviewshq.com for deluxe bark control collar review - For sure, the deluxe little dog bark control collar utilizes nano-technology to really make it light-weight and little so it fits pretty good on little and also medium-sized dogs. <br /><br />The patented technology makes sure a dogs bark will be the only sound that will activate one of the ten levels of static correction. The correction begins with the smallest degree and raises if barking continues. <br /><br />The collar also takes note of the level of correction that made the dog stop barking so once the dog barks again, the collar begins correcting at the remembered point. A safety time out will shut off the correction for 3 minutes when the dog barks over 15 times in 1 minute 20seconds. <br /><br />The new design is nylon web. Each collars fit neck sizes about 16-inch and dogs that weigh 8-55-pounds. It really works so well, and without any obvious pain on dogs. Like i said before, this thing is very light-weight and little and matches completely on dogs neck.
