Arcturus and Pollux (from) the Doomb dogs are the best pets in literature, while the dogs which accompanied the Akhaians are the bravest. Dogs should be considered as individuals whose characters must be judged on the basis of the qualities they express in their acts, making them 'best'. The only thing that could be 'better' would be if there was a dog's voice talking to you, and telling you this and you got to respond in the way I did.

A dog's perspective on his own greatness is a matter of POV. We don't see things from our own point of view, and neither should dogs (for example, we don't look at ourselves in mirrors, or hear our own voice on recordings.) Dogs have different ideas of what's good and what's bad. They may have a completely different set of values than what you consider moral, for example: even though dogs may believe that a human's death is a bad thing, they may believe in parallel that eating humans is a good, virtuous thing (and perhaps they may also believe that a human 'should' be eaten; and that would not be great)

Dogs don't believe in religion or anything outside of commands. Dogs can't believe in other things than food and water initially. They don't care. Cats on the other hand obviously care about religion, and perhaps also about politics, in which case I assume the cat that's not a cat's cat is a cat that's a cat's cat. That's why you need two or more. No dog every thrives alone.
