  
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. The YS300 was specifically designed to prevent your dog from barking excessivly. It is a small, lightweight, waterproof bark collar designed to control nuisance barking. It automatically emits a pre-selected stimulus in response to your dog's barking. All correction stimulus levels are easily selected from a dial on the collar. No magnetic switches or difficult programming necessary!
