Seth Pet - Smart Bark Collar Product Overview INTELLIGENT ANTI-BARK COLLAR: SethPet?s Bark Collar is the smart and humane way to bark train your dog. Waiting to correct until barks reach 1000-2000kHZ, 80-90db, our intelligent microprocessor ignores playful yips, barks of other dogs, or surrounding noise. The adjustable nylon reflective collar fits dog?s necks from 8 - 24 inches and is available in Fluorescent Yellow, Gray, and Black color varieties. PROGRESSIVE CORRECTION AND HUMANE PROTECTION: Designed to correct problem barking behavior not punish, progressive correction attempts to stop your dog?s barking before shocking?starting with an audible beep and followed by strong vibration. The humane protection mode deactivates the collar when static shock is triggered seven times in one minute. DUAL TRAINING MODES AND ADJUSTABLE SENSITIVITY: Tailor bark training to your dog with our dual training modes and adjustable sensitivity levels. With a one-touch ?M? mode-button, select between Shock or No Shock modes and adjust the collar?s sensitivity and intensity range to make training suitable for your dog.
