I'm so sorry for your loss hun, please know our thoughts are with you. There's never any way to make this time easy... the beauty in all is you were able to share some wonderful years with a beautiful friend. One thing I thought of and truly believe, is that these creatures are a God-send. They truly just dont live long enough. When I was going through the loss of such a wonderful dog in my life who seen me through many years and everything that goes along with them, I realized often they are with us just enough to truly effect your life in a positive way, and then they're gone, like an angel. She had been with me long enough to share in a lot of joy and be unbelievable comfort in the rough times, more than any person! She really was my angel. I'm sure your Cooper was the same... something about those Goldens particularly. (She was a golden/shepherd mix... more golden) They really seem to have that 6th sense.
