Anti-bark collar for small dogs

When worn, the jet anti-bark collar for small dogs from PetSafe® effectively discourages barking. The anti-bark collar features a unique patented sensor for the most reliable bark detection available. The collar uses a vibration sensor and a sound sensor (patented dual detection system) to distinguish barking from autres types of noise. The odorless spray is only sprayed if the system detects both vocal cord vibrations and barking sounds. For dogs over 3.6 kg and up to 26 kg
