I think I wrote all this before.  Our white Standard Poodle and I are a  'Therapy Dog'  team and visit three hospitals every week, including a very large nursing center, a large urban hospital and a separate children's hospital.  I wrap these necklace lights around her (same color)  collar and attach (same color)  bows and ribbons on her ears.  As I said, this is all a little tacky-pretty but it helps with some patients she visits.  Her job is to help patients focus on something beside their situation for a few moments and maybe to inject  agreeable, non-threatening topics among the visitors.
  These necklaces don't last very long but they do a nice job for the Christmas period.  I use other color ones for other times of the year.
