I cannot imagine why no one is looking for him!!! Whatever the case, I am SOOOOo glad you found him and took him in with such love and concern!!!! What are the odds of you finding a yorkie wondering around on the street when you already have two yorkies of your own!?!? I think everything happens for a reason....maybe that yorkie needed the love that you and your family can provide in his last years and it was no accident that he found you
I believe everything happens for a reason. May God bless you and your husband for taking him in
