Nanjing subway police welcomed two super small police dogs. What kind of dog will be chosen as a police dog?

I once saw a video on social news that police dogs dozed off on the subway. People have been sprouted by cute dogs, but this type of working dog has a high threshold, and not all kinds of dogs can be working dogs.

Seeing-eye dogs were mentioned in a movie "Pets" before. Guide dogs also have high requirements for dogs, such as absolute obedience, high IQ and meekness. Dogs that can meet these requirements are generally German Shepherd, Labrador and Golden Retriever. Especially Labrador as a guide dog, because Labrador should belong to the dog with the best personality, high IQ and high obedience.

Of course, it is also suitable for other working dogs. For example, drug detection dogs and police dogs have higher requirements for dogs than guide dogs, and such working dogs also require dogs to have a sensitive sense of smell. Dogs have a better sense of smell than people, and this kind of work will be put into daily work after training, and it is compiled.

I think the first dogs excluded by working dogs and police dogs are huskies, Bomei, Teddy, Samoyed, Shiba Inu, poodles, etc. These are just ornamental dogs. Although some of them are obedient, their IQ and personality are not suitable for working dogs, especially huskies, who are called stupid dogs. Dogs that are too energetic and too big are not suitable for working dogs, such as Tibetan mastiff and Alaska. They are too big to go out with the staff. Moreover, these large dogs are not very good in personality, don't listen to their owners, eat too much, and have high costs, so they are basically not working dogs.

I have seen a policeman raise huskies as police dogs and perform many tasks before, so it depends on the specific ability of dogs. Many dogs can still be chosen as working dogs if they can be trained.
