Heavy heart

We didn't go to the vet today.  I have an appointment tomorrow.  I know the end is near, but I don't want to lose him.  Duncan has eaten nothing today.  He has drank some water.  He moves ok.  I don't know what is wrong.  And I have no idea how old he is.  My vet thinks he is around 15-16 and he is probably right.  He also told me when I got Duncan, that he was around 8.  I think he was older than that.  Dr. Henninger put two and two together when I got him and said that he has been used in a puppy mill for breeding and when he got too old, they just put him out.  When he was found, the groomer that Chelsea took him to could not tell what breed he was.  His hair was so matted that he had a mummified cockroach in it.  she had to almost shave him.  He turned out to be a Maltese.  And I sat about giving him the best life.  He may have had a lousy first half of his life, but he has been a prince in the last half.  I love him so much.
