OK, Allison, this is my last suggestion.

Dammit.

Think of the ease when training the pooch: Sit, Dammit; roll over, Dammit. Dammit, come here. Dammit, put your back legs on the paper, not just the front. Hey, it's a natural.

Regardless what the dog's name ends up being, that is one cute AND intelligent dog. Just plain looks smart. He(?) will be your worst nightmare unless you give his brain lots of things to ponder and work out.
