The PetSafe PBC-102 Bark Control Collar is the simplest and one of the smallest bark control collars available! When your dog barks, this anti bark collar gives a warning beep and mild correction. Then if he continues to bark, he will receive the warning tone with a slightly stronger correction. This process will continue up through six levels of correction. The collar senses the vibrations in your dog’s throat that happen only during barking. While not at all harmful, the PetSafe Standard Bark Collar is an effective deterrent to excessive barking.

Features:
• One of the smallest receivers available at only 2.3 ounces.
• Sophisticated microprocessor technology provides a warning beep with the first bark.
• Six levels of progressive correction for stubborn dogs.
• Not too strong for small or timid dogs...yet strong enough for large or stubborn dogs.
• PetSafe PBC-102 also has automatic shut-off if your dog continues to bark more than 15 times in a 50 second period. The PBC-102 will then reset after 3 minutes.
• Lifetime Warranty.
