Robin from looking at these pictures I would say ...unless you really cleaned her up that she has not been running very long....and as her coat is in good condition....and she does not look like she missed too many groceries I would bet there is a family looking for her.  I know I would be frantic if my Molly was lost so hope you soon find her family.  Are you falling for Irish Setters? 

Hi Robin,

Just stopped by to see if you found the owner for your lost Irish Setter....sorry I did not see the comments under his photos when I posted before,  Hoping you find where he belongs soon.

Robin ,

  Have you contacted either Save Our Setters or the Irish Setter Club of America?  both foster Irish Setter's while waiting for new forever homes for them.  I am so sorry that this guy has not found his family...and bless you for taking him in to try to help him.
