How dog useful for us?

Different types of animals are helpful in different ways. Larger livestock animals such as horses or cows can be used instead of tractors and machinery to help do work around a farm. Horses are useful in some areas as a means of income through entertainment, such as horse racing in Kentucky.

Smaller animals are also helpful in therapy - horses are also frequently used in various forms of therapy. Dogs are most frequently used, although cats can also be seen helping hospital patients, or therapy patients. Most of the time, depending on the patient, dogs and cats have a very calming effect and help aid recovery by bringing smiles to faces and relaxation.

Dogs and horses both are used by the police force. Horses are used for transportation and occasionally even defense. Dogs are used to help find things, offense, defense, and general aid.

Animals are also used for food. For example, beef and milk from cows, chicken meat and eggs, and so on.
