In the rural areas, almost every family raises dogs, but the main purpose of keeping dogs is to guard the house. Nowadays, it has become a fashion to keep dogs in cities. Modern life is full of pressure and work is frequent; many people think that raising children is troublesome and affects their free life. Therefore, they raise dogs as pet companions. However, some dogs are not very obedient and bark incessantly all day long. This not only affects normal life, but also disturbs the neighbors, which is even worse. For such dogs, it is suggested that the dog owners put an anti-barking training collar on their dogs. Its function is to prevent dogs from barking at inappropriate times. It trains the puppies to control their barks and behaviors through sound warnings and slight vibrations, and it will not cause physical discomfort to the dogs. The current retail price is 6 dollars.
