Dogtra has developed a "sound recognition and filtering micro-processor" that distinguishes a dog's barking in its surrounding ambient noises. The Dogtra YS-300, an intelligent no-bark collar, is fitted with this self-activating micro-processing sound analysis technology, which only responds to the barking of your dog. This technology has been applied for patent and is now under Patent Pending.

This collar will work for small dogs to medium (sensitive) sized dogs.
