angel dog?

Friday I went to see a patient that had developed hallucinations.. was it medication? part of the dying process, just a lack of oxygen to the brain? I was talking with her, then in a matter of fact way said, "You know you have a long hair white dog with you." It was a small dog she said. Upon questioning her she decribed it as a white colored, short nosed little dog....does that sound like anyone we know.. change the color to black...love, mom
