Thank you for all the kind words about Murphy. It was awful, but there is no doubt in my mind that he was very near death, dehydrated and in pain. He looked nothing like that bright eyed little dog in the pictures here, or even how he looked ten days earlier. And without going into the ugly details I can also say that there was zero hope of his ever putting on weight or surviving further dental work. That was wishful thinking on everyone's part, including his vet. She had called me on Sunday afternoon, after thinking it over, and we were on the same page. He was in pain, his weight was plummeting despite pain meds and hand feeding, I suspect his kidneys were failing, and it was hopeless.
Knowing this didn't make it any easier, and losing him is as painful as losing a human family member. That tiny old dog left a big hole in the household.
