Well, you have to realize that AKC registered dogs have to have unique names, so they get kind of involved so:
The German Shepherds:
Chimanes mia zarifa balaniki
Chimanes Contessa
Carey Anne's midnight dreamer
Carey Anne's Lethal Weapon II
And the two mutts have simple ones
Tazer because he was full of energy as a pup
Winston Churchill because she (yes she) looked like WC as a puppy (ask my wife on this one).
