BP-504 Barkless Pro Advanced Anti Bark System.

Bark-Less Dog Collars-No Bark Dog  Designed for dogs that bark too much, the bark-less collar utilizes a proprietary low-current stimulation technique to humanely condition dogs not to bark.  Setting the collar to the correct level, protection barking will continue while unnecessary barking is eliminated.

Most of E-Collar Technology's bark-less, no bark collars have an auto-mode feature that senses the dog’s barking habits and automatically increases the stimulation until the barking has stopped. Our bark-less dog collars have a unique stimulation technology that provides very clean stimulation without the normal head jerking. Some of the other exclusive setting features include:

*Tone Stimulus Before Stimulation
*Limited Lifetime Warranty 
*Low Battery Indicator
   - Test Mode
   - 4 Different Levels of Stimulation
   - Auto-Mode to Allow Some Barking
*Adjustable Nylon Strap
   - Shock Resistant Waterproof Casing
*Small Enough for a 5 lb dog.
