So sorry to hear of your loss. These type of friends who ask nothing of us are so special. In a few weeks it will be the 4th anniversary of the day I had to have my Lab, Patches put down after 15 years. I will never forget because it was 2 days before the birth of my youngest daughter. We adopted another Lab a year later, but I still come home after work, grab the leash, and accidently call out the wrong name every now and then. The pain has gotten less, but the memories are strong as ever. I wish you the strength to get thru this, and hope that you find another dog to fill, but not replace, this hole in your life. He can never be replaced, but another dog would love to give and receive the love that you have to give.
