Company of Animals The Quiet Dog gently and effectively calms the urge to bark but is not a muzzle.  It is a simple to use face wrap that has been especially designed to help stop unwanted barking.  This lightweight and non-restrictive training aid can also be used for a variety of other problem behaviours such as whining, jumping-up, destructive chewing, digging and scratching and it is also the ideal aid to prepare your dog for wearing a head-collar.
