It's so cute to see a police dog wearing a mask on the subway. The dog sits by the police officer in an orderly manner, without any noise, and appears to be very obedient. Although it may be a little unsuited to the mask, it does not complain, but sits quietly in the corner. Some say it's really necessary for this dog to wear a mask?
Dogs are trained work dogs that are specifically designed to detect and solve cases. Their senses are well developed, their senses of smell, their hearing and their eyesight are so sharp that they can distinguish trace scents and sound and even see the goals of movement in the dark. Trained dogs also have the capacity to bite, run, protect their owners and adapt to all kinds of harsh circumstances. As a result, dogs play an important role in tracking, hunting, alerting, identifying the scent, arresting fugitives and collecting evidence. In everyday life, dogs don't bite. The man who was bitten by a police dog must be the bad guy. Whether the dog bites depends on whether the next conductor gives the order. In the absence of an order, dogs consider all persons to be good people. Moreover, dogs work hard, requiring six to eight hours a day.
So why do dogs wear masks? Actually, dogs wear masks to protect their safety. One is to protect dogs themselves, the other is to protect suspects. This has become a consensus among the police and is a common practice at the international level. Furthermore, while dogs do not wear masks and do not bite, in order to keep passengers from fear, dogs on the subway are required to wear masks when working. These dogs are really dogs that we should respect very much, because they have been serving the people.
