Are You Struggling with dog's excessive barking If barking is the primary issue with your pup, find a collar dedicated specifically to that issue. This bark collar uses dual recognition to make sure it activates only when your dog barks (it registers sound and the vibration of bark in your dog’s throat). This also prevents it from activating when a nearby dog barks. As noted, one reviewer said their dog got used to the collar’s vibration and still barks when the collar is off.
