I know how you feel. I had to bury my wolf pal a couple of years ago.
I have a rat terrier we call peanut. I came home from work the day after we got her at the pound and she met me at the door standing on her hind legs wanting to dance. So, dance we did, and from that point on her 'official' name is Ginger Rogers.
We seldom name pets right off because they will name themselves.
