What should I name my dog?

Midnight

Shadow

Maybe "Harbor", because of his blue eyes.

Blitz, Blitzer, Blitzie (depending on gender)

Or perhaps try looking at foreign names. I was once going to name my dog Ushio, which is a Japanese name.

Sky-Blue; Blinx; Cola-Blue; Indigo; Perry (for Periwinkle); Koda; Cayman (Cayman Islands have blue water surrounding them). 

Name it Jino.

Onyx, Styxx, Skylar (male version of Sky, as in blue skies)

Domino, Raven

"What Is This Bit?" would work.
