Name change

So, Polly does not seem to fit this little girl.  I thought I would be fine with it but she doesn't know her name PLUS, this is the name her breeder/idiot named her.  Therefore, I can't get the ickiness of saying this name to her as a reminder of where she came from, out of my head.  So, Nathan (my 13 yo son) asked me if we should change her name.  I said, that I wasn't sure. He said, "How about, Ruby?" I said "wow, that name seems perfect for her!" So I think that is what we will do. Ruby is her new name.
Here is a copy of the "pedigree Certificate" from her puppy mill past,  I have half a mind to burn it.
