Dogtra YS300 Yapper Stopper

Dogtra has developed a "sound recognition and filtering microprocessor" that distinguishes a dogs' barking from its surrounding ambient noises. The model YS300, 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.
