We had to put our little Yorkie down just before Christmas.  Her health was really going downhill in the past year.  We tried medication but the little thing lost much of her hair and it turned oily.  She lost weight and had chronic diarrhea.  Now we only have the two neighbor cats that think they live with us.    Probably because we feed them everyday give them a warm place to sleep in the winter (they are outdoor cats).  They each have a little basket to sleep in and we just bought a new "potty" for them.
