My son came to own a badly abused border collie "Elmo" about five years ago and we have come to love her very much. All we knew is she had not been fed so she killed gophers to survive and had to live in dog shelter with no heat even in the dead of winter. It took a lot convincing to get her to come into the house but since then she has become my son's faithful companion. This past Tuesday after spending a weekend watching her - it was obvious she was not well, he took her to the Vets to find out she had congestive heart failure. We will miss her!
