In this case, the owner can try to distract the dog's attention, use toys and snacks to divert the dog from chasing and yelling at passers-by, and wait for the dog to calm down before disciplining and restraining it. After that, be sure to wear a leash when taking your dog out. As long as the dog appears to chase or shout at passers-by, take the dog home immediately. Repeat the operation many times to achieve the corrective effect.
