He's soooo cute. Looks very happy in your house and I am sure he will bring you LOTS of smiles.
I would name him after something that has a meaning to you, from your childhood, from yesterday. And something that's easy to yell when he's ran out of the house or chewing on the comforter.
I named my dog Madeleine, and before you knew it it was Maddie and now its just Mad.
