A very difficult thing to go through for sure (have done it three times in the past six years). I find that focusing on all the happy memories helps a bit. Instead of thinking on the days near the end, I think of all the fun things we did together. I took my pups all over the place - Europe, Canada, and many places within US. Such good travel companions and endless fun together...I miss them all dearly - but I am now able to think about them and smile, knowing that I gave them all perfect lives. May your days become sunnier...
