Dogtra has developed a sound recognition and filtering micro-processor that distinguishes your dog's barking from its surrounding ambient noises. The Dogtra Yapper Stopper Anti-Bark Collar (YS-500) is an intelligent bark collar, which is fitted with this self-activating micro-processing sound analysis technology. The unqiue technology allows the collar to only respond to the barking of your dog.

This fully waterproof no-bark collar designed with the same reliable electronics found in the popular Dogtra remote training collars. The YS 500 features seven variable intensity settings that provide a wide-range of stimulation levels for any type of disposition. Designed for medium to large breeds. Long lasting rechargeable Ni-MH batteries, charger included. With proper repeated usage, your dog may be able to learn to stop barking with the vibration warning so that stimulation will no longer be necessary. A great solution for a dog training collar.
