One of my favorite subjects is a dog. They always have great faces sometimes more expressive than other times. It is a good thing when taking dog photos that you take a lot of shots, even one after the other because their expressions constantly change and it is always better to capture the one a little different than the same thing over and over. If you are patient, there will be one that is more pleasing than the others. An example is below. Memphis was just hanging out, but I caught him with his eyes looking up for a moment and that is what we have here. Looks better than the rank and file photo.
