Animals please their masters by maintaining an ambience of recreational pleasure. Animal sport is one of the major influences of their existence, and even they themselves get pleased by doing so (BEEP). Horseracing, Bullfighting, Greyhound racing, He-buffaloe racing etc. establishes a very important gig for the animals. Such events are very famous in many parts of the world, and it is quite virtuous to organise such occasions. Similarly, animals used for medical research assist the human advancement by testing new drugs and technologies on them. Use of a living human body for such purposes would be very unethical as humans are more important than any other animal in the world. Similarly, animals used for agricultural work and other related purposes pay their duties in certain perspectives. They ease the pressure of work, and they can finish the work in less time. Use of animals in every respect is essential. They should be used and that is how they fulfil the reason of their survival. Of course, there are increasing chances for an animal to get hurt, but that is a part of its work. A man can make them work more and more, it is not wrong.
Animals are for human use. They are important for the human survival. They can be used for anything like work, recreation, leisure, playing etcetera. It is not erroneous to make them work hard. They come to the world to serve humans.
