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.

Non-electrical stimulation vibration (P) warning prior to the stimulation. 6 intensity levels (2-7) for a wide variety of dispositions.

Rechargeable 2-hour rapid charge Lithium Polymer Battery.

Testing level (T) allows for testing of the collar without any electrical correction.

Fits dogs as small as 10 lbs. (receiver weight: 4.0 ounces)

Tri-Color LED Battery Life Indicator.

Fully waterproof.
