Isn't it interesting how, when a dog shows such extreme and unquestioning loyalty, we find it so adorable and endearing. When a person shows such loyalty, it can almost be off-putting!<p>Is it that people have so many hidden motivations you become suspicious, or worry about generating / reciprocating feelings of obligation, or end up disappointing you after causing you to invest emotion?<p>Or just that a "simple" animal can exhibit such complex behavior that we find especially endearing?
