My year-old little monster often does not answer to his name. I know that he HAS to know his name by now -- I say it about 1,000 times a day. But, if I say his name, instead of coming to see what I'm talking about, he just ignores me. Then, sometimes, I'll say "Archie" or "Archibald" and he will turn his little peanut head to look at me! Most of the time he just keeps doing what he's doing. Does anyone else have this problem? Or is my Yorkie a candidate for the "short bus?"
