Which animal makes a better pet? Why?

I think that it's dog. That has two reasons. First, I think dog is used to man. Cats or some animals, are not used to man too much. If we discipline dogs properly, dogs betoken it's fidelity. And if dogs are used to us, we can play together something to do. It's fun for us and dogs. In addition, if we tired, dogs mend. Second, dogs are almost omniorous. So we prepare their food easily. Either, goods for dogs are selled many shops now except foods. I think that important things to have pets are how used to and how easy to take care of.
