If we observe dogs we can realize lot of things that can be helpful for our lives. They are very faithful and want to be with the people they like at any situation, don't feed up theirselves if there is not need for it, have a great sense of adaptability, love others not caring for reward, when they are about to die they hide not to bother others, do things as simple as possible in order to not waste energies and rest if needed. Indeed, they are the best companion for a man.
*Doing this was REALLY hard for me...
