My wife and I got our first dog last year. I could not imagion how it must feel as he is such a part of our family. I'm very sorry to hear of your loss and can only hope that time will heal these wounds.
Nearing this decision with our dog, Jake, also a yellow Lab. He's almost 14 and has cheated death for a while now. We also have a 3-year-old chocolate Lab and I seriously think Jake doesn't want to let the little bastard win!
Sorry to hear about your loss and wishing you comfort.
I, too, had to put down my best friend earlier this year - and unexpectedly to boot. I am so sorry for your loss and feel your pain. It is so difficult. Dogs become part of the family and with unconditional devotion and love we attach to them so easily. I am sure you have many wonderful times to remember!
