Is it good for dogs to wear bells?

Pros and cons of wearing a dog bell: There are advantages and disadvantages to wearing a dog bell. The advantage is that when you go out for a walk, you can know where the dog is to prevent it from getting lost. At the same time, it can also remind passers-by that a dog is passing by. The disadvantage is that the dog's hearing is relatively sensitive. Sometimes the sound of the bell is loud, which makes the dog uncomfortable, so it has some psychological and mental effects. Animal owners can take them off when they are at home and put them on when they go out. It is better to choose some bells that are not harsh. Dogs (Latin Canislupusfamiliaris) belong to the phylum Chordata, the subphylum Vertebrates, the class Mammalia, the subclass Eutheria, the order Carnivora, the suborder Schizopoda, and the family Canidae. Also known as "dog" in Chinese, dogs are distributed all over the world. Dogs, horses, cattle, sheep, pigs, and chickens are collectively known as the "six livestock". Some scientists believe that dogs were domesticated from gray wolves by early humans, and the domestication time ranged from 40,000 to 15,000 years ago. Known as "man's most loyal friend", it is the most frequently kept pet, with a lifespan of approximately 12 to 18 years. In Chinese culture, the dog is one of the twelve animals in the zodiac, ranking 11th among them.
