Efficient barking control, scientific behaviour guidance Intelligent sensing technology: The device has built-in high-precision sound sensors to accurately identify barking dogs and trigger ultrasonic or vibration reminders to interrupt undesirable behaviours in a timely manner and avoid ineffective stimulation. Gentle training mode: ultrasonic, vibration and other physical stimulation methods, no electric shock injury, in line with animal welfare standards, to help the dog to establish a barking - discomfort negative feedback conditioned reflex, and gradually reduce the frequency of barking. Multi-scene application, flexible response to demand Indoor and outdoor dual mode: support handheld portable (such as walking anti-interference) and fixed installation (such as courtyard anti-neighbour complaints), covering home, park, street and other scenes. Waterproof and durable design: IPX4 waterproof material, adapt to rainy days or wet environment, outdoor use without pressure. Humanised design for safety and comfort Adjustable sensitivity: Adjust the trigger threshold freely according to the dog's size, personality or environmental noise to avoid false triggering or over-stimulation. Low battery reminder: Equipped with a battery indicator light to warn of charging needs in advance to avoid interruption of use. Auxiliary Training Functions to Enhance Training Efficiency Positive incentives: It is recommended to combine with positive reinforcement methods, such as snack rewards and command training, to consolidate the effect of anti-barking and form a positive cycle of quietness-reward. Data recording and analysis: Some high-end models support barking statistics to help owners analyse the causes of barking (e.g. anxiety, territorial awareness) and adjust the training programme accordingly.
