Sorry for your loss Lee. We went through the same thing several years ago with our Rotty named Jake. He got sick and we had him checked out and it turned out to be cancer in his stomach. The Vet removed it all but he never recovered and began eating again. The Vet, a friend of mine came by on a Saturday afternoon, after we had tryed everything anyone knew to do, and did what was needed to be done. We knew this was coming and I made him a casket to be placed in and we buried him in our backyard. He was a great friend, a very royal companion, and never gave us any problems. That was 10 years ago and still chokes me up. Not much on crying either, but I cryed like a baby when he died. We did everything we could for him and I do not regret that at all and would do it again for him, but in reality it was his time to go.
Again so "Sorry" for your loss,
Ray
