I think, for some necessary reasons, like eating, we should trained some animals. But not the all.Should Animals Be Trained to Help Humans? Nowadays, animal housekeeper and animal guarder are not news. Animal training has begun almost in every country, but should animals be trained to help humans? In my opinion, the answer is yes.

For example, we train monkeys to take care of the quadriplegics, train dogs to lead the blinder as guiders and so on. In a word, we need animals’ help。 animals should be trained to help humans.
