The YS 300 is a bark activated, intelligent no-bark collar for small to medium sensitive dogs. Dogtra has developed a "sound recognition and filtering microprocessor" that distinguishes a dogs' barking in its surrounding ambient noises. The model YS300 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.
