• Anti-bark collar with two operating modes: sound and vibration, designed to safely and effectively train dogs of different sizes. • The device automatically detects barking and emits a sound warning; if the dog continues barking, from the third bark onwards, vibration is added to the sound. • Features 7 adjustable sensitivity levels to adapt to the volume and duration of each dog's barking. • The strap is adjustable and has white reflective bands for greater visibility and safety at night. • Incorporates intelligent sensors and chips that detect barking through throat vibration, preventing activation by other sounds or dogs. • The collar activates quickly and accurately, reducing false triggers. • Long-lasting battery allows use for more than two weeks without frequent recharging. • Comfortable and practical design, easy to put on and take off, with plastic contact protectors to prevent chafing on the dog's neck. • Ideal solution for people who want to correct their dogs' excessive barking habits in a simple and safe way.
