Lost my little doggy.

I have had to put down livestock myself more than a few times over the years, and yes you get attached to that old moma cow that served you so well, a good horse that has always done his job becomes a member of the family. I can love a faithful cat, independent as they can be. But it is something about that special dog.
I can't stand to think that my old dogs last moments are without me, but the look he has in his last moments are so difficult. But life is a circle,and we all make that circle/
