What a great-looking dog - smart, attentive, and definitely hoping for a place in your pack.
Snubbie?
Shame he's not a she... if so, you could have called her Lady(smith).
In my experience, dog names always change over time, becoming more informal and going high at the end (I'm told because dogs respond to high tones, and over time, you choose those nicknames they respond to). Thus, if you called him Remington, over time it would change to something like Remi or Remy (which may already have been suggested), which would not be bad, either.
