Rupert B. Puppenstein is a name that my fiancee came up with. I love the name Rupert, his registered name is Cobweb's Butch is a DeLite, but I didn't like the name Butch and felt guilty not keeping it with him as he was his breeders baby first, so the B. stands for Butch, and my fiancee came up with Puppenstein because he didn't think BT's were cute in the beginning and looked a little frankenstein-like. We call him RBP for the most part or Rupert. But to his doctors and our friends and family, he is known as Rupert B. Puppenstein.
