Wearable devices designed to reduce or stop a dog’s barking behavior, commonly called “anti-crying necklaces,” are on the market. These devices inhibit or correct the barking behavior of dogs using various technologies.

First, the vibrating necklace distracts dogs by making light vibrations when they bark. It is considered to be a relatively non-invasive method, which is physically harmless. Another way is through an ultrasonic necklace. This emits ultrasound, which is inaudible to humans, when it detects a dog barking, to attract the dog’s attention or stop barking. Ultrasound can be unpleasant to dogs, but it is not harmful to their health.

When a spray necklace detects a bark, it stimulates the dog’s sense of smell by spraying a harmless spray, such as citronella, near the dog’s nose. This method can be effective in distracting the dog and reducing its bark. On the other hand, an **E-collar** is a method that provides electrical stimulation when a dog barks, which can be effective in reducing bark, but is controversial because it has the potential to stress the dog. The device should be used carefully.

Recently, smart training wearables using AI and sensors have also appeared. The device provides responses that are appropriate for a situation by analyzing a dog’s behavior and identifying the cause of its bark. For example, the anti-bark function can be set to work only in certain situations.

Safety and effectiveness should be considered first when choosing anti-bark wearables. As the effectiveness of the wearables can vary depending on the dog’s size, personality, and barking cause, it is important to choose a product that fits your individual situation. In particular, controversial methods, such as electronic shock necklaces, should be used carefully only when absolutely necessary.

After all, these wearable devices can help reduce barking behavior, but solving the underlying cause is most important. The reasons why a dog barks can vary, such as alertness, stress, boredom, or illness, so it is effective to combine sufficient exercise, mental stimulation, and positive training with behavior correction. This can help maintain a healthy and harmonious relationship with your dog.
