None of mine had an official middle name - just lots of nicknames that got tacked on after the first name, every so often. The only exception was 2 of my Lhasa Apsos from many years ago who were AKC registered, and had official longer names. The girl was Tai Ling Soo, and her son was Wei Wooli-Bear. Of course RB Myndi was registered too, and she was Myndi-Jo Kong - and a lot of nicknames too. Sparky was a half-breed tho, you would never know just by looking at him. He had a lot of the silly names too. Wolfy has a few silly names that he is called at times in addition to just Wolfy-------------The Wolfman, Wolfenheimer, Wolfenstein, Melonhead, Twinkletoes. I'm sure he wouldn't like it that I revealed the Twinkletoes name - afterall -it isn't very manly sounding. He picked up that name since the 2 middle toes on both of his back feet are white, and really "twinkle" against the rest of the dark fur that he has.
